Physics News
The following students have passed their Ph. D. or Master examination successfully:
Ph. D.:
Sangita S. Kalarickal successfully defended her thesis “Ferromagnetic relaxation in
(1) metallic thin films and (2) bulk ferrites and composite materials for microwave and
information storage device applications” on April 21, 2006
In April, 2006, Tao Li became a Caltech Postdoctoral Scholar at Jet Propulsion
Laboratory, California Institute of Technology. Tao will work on the technology and
science of the JPL water vapor Raman lidar, as well as the scientific study of the
mesospheric temperature tides as observed by the JPL lidars. Tao received his PhD in
2005 and served as a postdoc in the Lidar Group at CSU under the supervision of Joe She
and David Krueger.
Dennis Agosta has accepted the job of Assistant Professor of Physics at Albertson
College of Idaho in Caldwell. Albertson is a small, liberal arts college with a total
enrollment of about 800 students, and they have plans to grow to about 1200 over the
next few years. He will be teaching Quantum Mechanics, General Physics (algebrabased), and Thermal Physics in his first semester.
At the national team meeting related to CuInSe2 solar cells in early April, former student
Markus Gloeckler, gave a presentation on work done at Colorado State last summer.
The talk predicted the changes to be expected in solar-cell performance as its absorber
layer is made progressively thinner.
At the World Conference on Photovoltaic Energy Conversion in Hawaii (early May),
PhD student Samuel Demtsu presented his work on the role of copper doping in the
contacting and the materials quality of CdTe solar cells. At the same conference, Jim
Sites presented a joint paper with colleagues in Slovenia on how power from hotovoltaic
modules integrated over a year under field conditions in Colorado and Europe compares
with that predicted by the standard conditions used to rate modules.
At the end of May, Jim Sites will give an invited talk at the European Materials Research
Society (E-MRS) meeting in Nice, France, on two different strategies to improve the
voltage of CdTe solar cells. PhD student Jun Pan did the calculations for the talk and is
a co-author on the manuscript that will be published.
The first ORNL (Oak Ridge National Laboratory) Clifford G. Shull Fellowships were
recently awarded. Sponsored by ORNLs neutron scattering facilities, appointments were
presented to Andrew Christianson and Wei-Ren Chen. Both gentlemen will be joining
ORNL in May of this year. Andrew Christianson received his Ph.D. in 2003 from
Colorado State University, where he majored in physics. He is currently completing
postdoctoral work with Professor Jon Lawrence at the University of California at Irvine
and as a guest scientist at Los Alamos National Laboratory (LANL). Christianson will be
assigned to HFIR.
ORNL established the Shull Fellowship to recognize Shulls pioneering work in neutron
scattering. Co-recipient of the 1994 Nobel Prize in Physics, Shull began his work in 1946
at what is now ORNL. The goal of this fellowship is to attract new scientific talent to
ORNL for the development of its neutron science program. The selection committee
looked for candidates with exceptional ability who were capable of developing
innovative research programs and who showed the promise of outstanding leadership.
Frank Winkelmeier, who got his Ph. D. here at Colorado State University (Advisor:
Walter Toki ), is the recipient of the very prestigious CERN fellowship. Walter Toki
recruited Frank during his stay at the University of Ulm, Germany, in 2002 where he
taught a class on particle physics within the framework of an exchange program of
professors we have established with the University of Ulm.
Eight members of the Carl Patton’s Magnetics group attended the recent INTERMAG
Conference in early May in San Diego. Jaydip Das presented a talk on barium ferrite
films produced by pulsed laser deposition. Sangita Kalarickal presented a paper
ferromagnetic resonance (FMR) in Fe-Ti-N films. Pavol Krivosik and Heidi Olson
presented separate papers on high power FMR in Permalloy thin films. Nan Mo
presented a poster on the classical theory of spin wave dispersion bands. Kumar
Srinivasan presented a paper on intergranular interactions in thin films. Mingzhong Wu
presented a poster on random solitons. Carl Patton spent all of his time either attending
or preparing for IEEE meetings. Bummer (for Carl).
The summer finds several new faces in the Magnetics group. Arkajit Roy-Barman, a
second year graduate student, joined the group for the summer. He is working with Scott
Brown on the e-beam deposition system and FMR measurements on metal films.
Physics major, David Kemp, also joined the group for the summer. He is working with
Daydip Das on the growth of barium ferrite films by liquid phase epitaxy. David is also
testing the new "Teach Spin" gyroscopic precession experiment that features a air
suspended spherical magnetic moment in an applied field. A lot of neat experiments for
Advanced Lab should be possible with this equipment. Sam Sun and David Flook from
Poudre High School have joined the group for the summer on the ongoing Research
Engineering Apprenticeship Program (REAP). Sam is working with Scott Brown on the
fabrication of the e-beam system. David will likely work with Mike Kabatek, Kevin
Smith, and Mingzhong Wu on soliton experiments. Shamil Assylbekov, a new
graduate student, from Kazakhstan, will also be joining the group for the summer.
After a round of celebration parties after the graduation ceremony in May, Sangita now
lives in Berlin. There is a good chance that she will be able to join the magnetics group
at the Free University of Berlin. In July, Kumar Srinivasan will leave the group to join
the Data Storage Institute in Singapore.
Recent visitors in the Magnetics group include Jeff Young from the University of Idaho,
Ming Chen from Boeing Aerospace in Seattle, Bill Czajkowski from West Point, and
Mark Hoefer from CU. Ming gave a department colloquium on phased array radar. Bill
is thinking about joining the group for Ph.D.work in 2007. Mark gave a group seminar
on spin momentum transfer in point contact magnetic film structures. He recently
received his Ph.D. at CU under Mark Ablowitz and is joining the Magnetics Group at
NIST as an NRC Postdoctoral Fellow.

Contribution of Alumnus — James Sherman
Professor of Physics/Electro-Optics, Indiana University of Pennsylvania
My road to Colorado State University
and beyond was a bit non-traditional and
long. I first attended college in Wisconsin, mainly to participate in athletics. I
earned a finance degree in 1990. After a
short and un-fulfilling venture into the
business world, I picked up a physics
text sent to me by my older brother-a
professor of Electrical Engineering at
Iowa State University. It looked interesting so I decided to pursue an education
in physics. After completing my BSPhysics degree at Iowa State University,
I attended the University of Rochester,
where I received an MS degree in Optical Engineering. During this time I also
took a few years off to work at Rockwell Aerospace (Canoga Park, CA)
where I worked on developing thermally-compensated Nd:YAG laser resonators. During this time, we also
adopted our eldest son J.J. I was offered
a permanent position at Rockwell after
graduation and was nearly set to accept
it. At the same time, I also applied to the
physics department at CSU-after coming
across a few lidar articles written by
professors Chaio (Joe) She and David
Krueger. I flew to Fort Collins to meet
Joe, David, and other CSU professors.
The faculty research interests seemed
exciting to me. Even more impressive
was the type of people making up the
department and their genuine concern
for students. The beauty of Colorado
certainly helped make the decision easier. My family and I immediately decided to move to Fort Collins, where I
spent the next 5 years completing
coursework and working in the CSU
atmospheric lidar group.
Constructing a hologram with my son Nikolaus
My research contribution to the CSU
Sodium Doppler Lidar system involved
hardware upgrades to the transmitter,
which helped lead to the capability of 2beam measurements. These upgrades,
combined with those of many other present and past graduate researchers (not
to mention Dr. She and Dr. Krueger)
have resulted in a novel laser system
capable of high-resolution temperature
and wind measurements in the
mesopause region. After 15 long years
and countless graduate students, the
group can now expand its energy on the
more scientific important study of atmospheric dynamics, in addition to ex-
IUP Physics student Scott Mettlen demonstrates his holographic optical
element project at undergraduate poster session-held 4/28/06 in our labo-
isting climatology studies. Several scientifically-relevant studies have been
conducted based on this data. These
studies involve the influence of atmospheric tides, wind shears, and thermal
structure (and their inter-relationships)
on atmospheric dynamics. Since completion of my dissertation in August
2002, I have worked with Joe on a few
more publications dealing with statistical analyses of atmospheric instabilities.
When combined with other works in the
field, such results will hopefully lend a
bit more insight into the highly-variable
thermal and dynamical structure of the
mesopause region.

Contribution of Alumnus — James Sherman
(continued)
After completing my dissertation, I accepted a faculty position at Indiana University of Pennsylvania, a small (14,000
students) liberal arts college located one
hour north of Pittsburgh. My role was to
develop the curriculum and structure for
a newly-created Electro-Optics program,
offered within the physics department.
The program is the only program in the
country which simultaneously awards
both 2 and 4-year degrees in ElectroOptics/Applied Physics. The difficulty
in teaching such a diverse population
(without the benefit of level-appropriate
instructional materials) has necessitated
the development (and refinement) of 6
lab manuals and texts, resulting in the
postponement of research until now. As
such, I would not recommend our model
as a template to other universities. I
now appreciate the Herculean task taken
on by Brian Jones at CSU and recommend that CSU give him a lofty pay
hike. We also recently received funding
to develop an electro-optics pipeline
with local high schools. I developed
curriculum for 4 optics and electronics
courses-which high school students can
enroll in and receive up to 12 college
credits. This will hopefully increase the
quality of our undergraduate student
population.
Now that the program is beginning to
evolve, I am initiating research involv-
ing the use of narrow-bandwidth lasers
to study the atmosphere. I will spend
this summer at Hanscom Air Force Base
in Boston (as part of an Air Force fellowship) working on transmitter development for a water vapor/aerosol lidar
profiler. This will be used to measure
the effect of laser scattering and absorption by water vapor and aerosols on
high-energy laser beam propagation.
Applications include military and freespace optical communications. My goal
in this research is to build on the experience obtained (as well as that obtained
at CSU) to initiate a long-term research
program studying atmospheric water
vapor and aerosols, and their impact on
climate and public health. The variability and optical properties of aerosols is a
limiting factor in development of accurate climate models, which in turn are
necessary to accurately predict the impact of man’s activities on climate. Proposed studies will initially involve insitu measurements (using scattering and
spectroscopy) to deduce optical properties of different types of aerosols. Lidar
development is more difficult at a small
undergraduate university, necessitating
collaborations with other lidar groups.
The quality of education and research
conducted within the Physics department at CSU is excellent. Faculty are
hard-working, caring, and professional. I

would highly recommend the department to any prospective students. That
being said-it is up to the student to make
the most of the opportunity. One of my
biggest regrets is that I became too absorbed in my own role in the project to
take advantage of the scientific expertise
of my advisors. I would recommend that
graduate students first obtain an understanding of the ‘big picture’, including
the scientific background and project
goals. This will result in a greater understanding of the student’s research and its
role in the project. It also will help the
student to better understand the meaning
of research and the factors involved in
turning a research idea into a funded
research project. The faculty advisors
are more than willing (from my own
experience) to help their students develop these skills. Where this leads is
dependent on the maturity and motivation of the student. With my 20/20 hindsight, I only wish that I had taken better
advantage of the knowledge and helpfulness of Dr. She and Dr. Krueger.

What is a Lidar ?
LIDAR (Light Detection and Ranging;
or Laser Imaging Detection and Ranging) is a technology that determines
distance to an object or surface using
laser pulses. Like the similar radar technology, which uses radio waves instead
of light, the range to an object is determined by measuring the time delay
between transmission of a pulse and
detection of the reflected signal. LIDAR technology has application in
geology, seismology, remote sensing
and atmospheric physics.
"ALSM," standing for "Airborne Laser
Swath Mapping," is another name for
Lidar. The acronym LADAR (Laser
Detection and Ranging) for elastic
backscatter lidar systems is mainly used
in military context. The term laser radar is also in use but somewhat misleading as laser light and not radiowaves are used and thus should be
avoided.

Visit of Physics and Chemistry Students
from Roosevelt High School
On Wednesday, April 12, 2006, Adam
Beehler hosted a visit of about 25 physics and chemistry students from Roosevelt High School. They experienced a
full introductory physics laboratory on
waves where they did the lab just like
college students would. Then Brian
Jones talked to them about college life
and career/financial opportunities. Next
they sat in on Richard Eykholt’s
PH111 (general physics) lecture. After
they experienced lunch at the Student
Center, they toured two physics research
labs. Erica Snow shared with them
Steve Lundeen’s atomic beam lab, and
Kevin Smith and Sangita Kalarickal
shared with them Carl Patton’s magnetics lab. Before they left for home,
Adam Beehler showed them around the
rest of the Engineering Building, where
they could see the many engineering
labs.
Adam Beehler is demonstrating an electrolarynx in lab. The harmonic frequencies
of the electrolarynx are sent into the vocal tract where some will resonate more
strongly than others.
The high school teacher, Brian Wells,
told me that one reason for doing this
field trip is to simply show his students
that going to college does not have to be
intimidating. Here is what Brian Wells
had to say himself, “I would like to have
my students participate in a college level
physics lab... This would have a great
positive impact upon my students, as it
did last year. And if at all possible
could my students sit in on a freshman
physics classroom lecture? These two
experiences will be tremendous in allowing my students to essentially walk
in the steps of a college student for a
day. [referring to last year’s trip] This
was a wonderful activity for that group
of students, several of which are now at
CSU as a result of that day.”
Adam Beehler and high school students are watching an oscilloscope software program to investigate different sounds, waveforms, and frequencies.

urements, and applicability of simulation work to cell development.
The experimental techniques include:
◆ Current-Voltage
characterization in
the dark and under illumination,
which allows one to measure a solar
cell’s conversion efficiency.
◆ Spectral
Response, the quantum efficiency, or electrons delivered to the
load per incident photon, as a function
of wavelength.
◆ Capacitance
vs. frequency or voltage
and temperature can establish the doping level and identify some active
defects in the forbidden semiconductor band gap.
Thin-Film solar cells are a promising
alternative to traditional Si wafer cells
for their lower production cost and material consumption. However, the technology for thin films based on CdTe and
Cu(InGa)Se2 is not as mature. The
Photovoltaics group at CSU works to
develop a physical understanding of
properties peculiar to the thin-film structures.
◆ Laser-Beam-Induced
Current (LBIC)
identifies non-uniformities in the cell
response, which can arise from variations in layer thickness, alloying,
shunt paths, and local variations in
contact quality.
◆ Reflection
and transmission measurements give information allowing the
improvement of optical characteristics, e.g. glass transparency.
People
Prof. James Sites has advised the photovoltaics group at CSU since 1974. The
group currently has seven graduate student members: Samuel Demtsu (back
contacts of CdTe solar cells), Caroline
Corwine (photoluminescence identification of defect levels in CdTe), Ana
Kanevce (measurement and theoretical
simulation of very Thin CIGS cells),
Tim Nagle (Laser-Beam-Induced Current [LBIC] studies of CIGS and CdTe
cells), Jun Pan (improvement of opencircuit voltage though theoretical simulation of CdTe solar cells) Alan Davies
(LBIC studies of stability in CdTe
cells), and masters student Galymzhan
Koishiyev. This summer the photovoltaics group will be hosting an undergraduate intern as well.
Research
We use precision measurement techniques and numerical simulations to
understand the physical mechanisms
controlling the performance of thin-film
solar cells and analyze sources of conversion loss. Emphasis is placed on
reproducibility and accuracy of meas-
Happenings
Alan Davies passed his PhD qualification exam on May 3rd, titled,
"Applications of Laser-Beam-Induced
Current (LBIC) to CdTe Solar Cells".
The week of May 7-12 saw Professor
Sites, with Samuel Demtsu, traveling to
Kilo, HI, for the 4th IEEE world photovoltaics specialists’ conference, where
they both presented posters of recent
projects and collaborations.
Sam Demtsu will be defending his thesis: “Impact of Back-Contact Materials
on Performance and Stability of CdS/
CdTe Solar Cells” on June 14th. His
work at the National Renewable Energy
Laboratory (NREL) on back-contact
materials for CdTe solar cells has improved the understanding of the influence of non-stoichiometric layers on
electrical performance. He has also
worked on the mechanisms of degradation of solar cell contacts with exposure
to simulated environmental conditions.
Caroline Corwine’s thesis is titled:
“Role of a Cu-O Defect in CdTe Solar
Cells” and she will be defending June
16th. Caroline also has done work at
NREL using photoluminescence techniques to identify a solar cell performance limiting defect in CdTe associated
with Cu and O impurities.
Theoretical calculations include:
◆ Energy
band structure simulation using AMPS 1-D, developed at Penn. St.
University. The program allows the
user to vary materials parameters
(doping, defect density and energy,
contact barriers, optical absorption,
etc.) in accordance with measured
quantities and then to explore how
variations in parameters will affect
device performance.
◆ Simulations
including interface properties and capacitance using SCAPS
simulation software from the University of Gent in Belgium.

Induction into Sigma Pi Sigma, the Physics Honors Society
This year, eight new members were
inducted into Sigma Pi Sigma, which is
the Physics Honor Society connected
with the Society of Physics Students.
The new members, along with a few of
their accomplishments, are listed below.
The induction ceremony took place at
the annual barbecue sponsored by the
Society of Physics Students (SPS) using
funds raised by them from various activities throughout the year. The barbecue took place at Watson Lake, near the
town of Bellevue, on Friday, April 28.
All undergraduate Physics majors and
minors were invited, and about 40 students were in attendance.
Eli Adams is majoring both in Physics
and in Chemistry and minoring in
Mathematics. He has done undergraduate research with Ellen Fisher in the

What's happening in the Magnetics Group - Carl Patton
05 June 2006
People
Sangita Kalarickal successfully defended her thesis on ferromagnetic resonance relaxation in bulk
and thin film magnetic materials.
Eight members of the group attended the recent INTERMAG Conference in early May in San Diego.
Jaydip Das presented a talk on barium ferrite films produced by pulsed laser deposition. Sangita
Kalarickal presented a paper ferromagnetic resonance (FMR) in Fe-Ti-N films. Pavol Krivosik and
Heidi Olson presented separate papers on high power FMR in Permalloy thin films. Nan Mo
presented a poster on the classical theory of spin wave dispersion bands. Kumar Srinivasan
presented a paper on intergranular interactions in thin films. Mingzhong Wu presented a poster on
random solitons. Carl Patton spent all of his time either attending or preparing for IEEE meetings.
Bummer (for Carl).
Arrivals
The summer finds several new faces in the group. Arkajit Roy-Barman, a second year graduate
student, joined the group for the summer. He is working with Scott Brown on the e-beam deposition
system and FMR measurements on metal films. Physics major David Kemp also joined the group
for the summer. He is working with Daydip Das on the growth of barium ferrite films by liquid
phase epitaxy. David is also testing the new "Teach Spin" gyroscopic precession experiment that
features a air suspended spherical magnetic moment in an applied field. A lot of neat experiments
for Advanced Lab should be possible with this equipment. Sam Sun and David Flook from Poudre
High School have joined the group for the summer on the ongoing Research Engineering
Apprenticeship Program (REAP). Sam is working with Scott Brown on the fabrication of the ebeam system. David will likely work with Mike Kabatek, Kevin Smith, and Mingzhong Wu on
soliton experiments. Shamil Assylbekov, a new graduate student, from Kazakhstan, will also be
joining the group for the summer.
Departures
After a round of celebration parties after the graduation ceremony in May, Sangita now lives in
Berlin. There is a good chance that she will be able to join the magnetics group at the Free
University of Berlin. In July, Kumar Srinivasan will leave the group to join the Data Storage
Institute in Singapore.
Visitors
Recent visitors include Jeff Young from the University of Idaho, Ming Chen from Boeing Aerospace
in Seattle, Bill Czajkowski from West Point, and Mark Hoefer from CU. Ming gave a department
colloquium on phased array radar. Bill is thinking about joining the group for Ph.D.work in 2007.
Mark gave a group seminar on spin momentum transfer in point contact magnetic film structures.
He recently received his Ph.D. at CU under Mark Ablowitz and is joining the Magnetics Group at
NIST as an NRC Postdoctoral Fellow.
Papers and Publications
Papers and publications: Mingzhong Wu's paper on soliton fractals has appeared in Physical Review
Letters (PRL) and a second paper on random solitons has been accepted by PRL. Sangita
Kalarickal's paper on FMR linewidth measurements by different methods has appeared in J. Appl.
Phys. and a second paper on the microwave properties of composite materials has been resubmitted
after review and critique. Three papers are currently in the review and editing stages, one on high
power FMR in metal films with Heidi Olson as the lead author, one on the cloning of spin wave
pulses with Kevin Smith as the lead, and one on the magnetic properties of Fe-Ti-N films, with
Jaydip Das as the lead. Four papers are in preparation, one on Fermi-Pasta-Ulam recurrence by
Mingzhong Wu, one on intergranular interactions in magnetic films by Kumar Srinivasan, one on the
hamiltonian formulation of two magnon loss in magnetic systems by Pavol Krivosik, and one by
Kyoung-Suk Kim on FMR and spin wave resonance in films comprised of ferrite pillars in a
ferroelectric matrix.
Programs
The new project for DARPA (Defense Advanced Projects Research Agency) to make composite and
multilayer thin films of ferrites and ferroelectrics started in mid-May. Postdoctoral Fellow Jaydip
Das is planning on ways to make targets to fabricate Phase I composite films. Funding has also been
promised (but not yet seen) on the continuation of the ONR (Office of Naval Research) microwave
ferrite/thin film program. The current MURI (Multi-University Research Initiative) on
electromagnetic wave science for battlefield communications is entering year 3 out of the total five
year program. The program to develop a prototype FMR system for the University of Idaho is near
completion.
Group meetings are generally held twice a week. For the summer, the scheduled meetings are on
Tuesdays and Thursdays at 10 am - 12 noon. Students and visitors are always welcome. Web
surfers are also welcome to check out the group web site expertly designed and managed by Pavol
Krivosik. http://www.physics.colostate.edu/groups/maglab/
