Grading
• 70% Oral Exam
• 20% Presentation
• 10% Class Participation
Project Assignment: Special topic student presentation and report.
You will prepare a special topic student presentation and report describing a new/original idea that you develop.
Details: Depending on the class size, students work as individuals or in a small group (group size <= 2).
At the beginning of the semester you sign up for a topic of your choice. You review the selected area and propose a research
activity in a 15 minute long talk + 5 minutes questions.
Together with your oral presentation you hand in a 1-2 page long report to pitch the idea. Originality, ability to present the
idea, and ability to provide scientific sound answers to questions are learning goals.
The topics are as follows: (2) NanoScale Imaging, (3) Conventional Nanoscale Lithography/Patterning, (4) Unconventional
Nanoscale Lithography/Patterning, (5) Nanomaterials: Properties, Synthesis, and Applications , (5) Nanoelectronics using
Nanomaterials , (6) Nanosystems manufacturing: Heterogeneous Integration and Self-Assembly, (7) own topic in the field of
Nanotechnology.

Homework 1: (Due in next class) Name:
1.Read the lecture on nanotechnology by R.P.
Feynmann, "There's Plenty of Room at the
Bottom":
http://www.zyvex.com/nanotech/feynman.html

The vision
The classic talk: “There's Plenty of Room at the Bottom ”Richard Feynman,
December 29, 1959. The annual meeting of the American Physical Society at
Caltech
•“Why cannot we write the entire 24 volumes of the Encyclopedia Britannica on
the head of a pin?”
•“Biology is not simply writing information; it is doing something about it. A
biological system can be exceedingly small.”
•“I want to build a billion tiny factories, models of each other, which are
manufacturing simultaneously, drilling holes, stamping parts, and so on.”
The vision (A)
Nanostructures:
a. Contain a countable number of atoms
b. Suites for atomic level detailed engineering
c. Provide access to realms of quantum behavior that is not
observed in larger (even 0.1 µm) structures
d. Combine small size, complex organizational patterns,
potential for very high packing densities and strong lateral
interactions, and high ratios of surface area to volume.
The vision (B)
Small => …means not only x1000 smaller but also….
a. High packing density
b. Potential to bring higher speed to information processing
c. Higher area and volumetric capacity to information storage.
d. Dense packing is also the cause of complex electronic and
magnetic interactions between adjacent (and sometimes
nonadjacent) structures.
e. The small energetic differences between the various
possible nanostructures configurations may be significantly
shaped by those interactions.
Vision….(C)
New established disciplines:
Electronics: nanostructures represent the limiting extension of Moore’s law
and classical devices to small devices, and they represent the step into
quantum devices and fundamentally new processor architectures.
Molecular biology: nanostructures are the fundamental machines that drive
the cell —histones and proteosomes—and they are components of the
mitochondrion, the chloroplast, the ribosome, and the replication and
transcription complexes. In catalysis, nanostructures are the templates and
pores of zeolites and other vitally important structures.
Materials science: the nanometer length scale is the largest one over which a
crystal can be made essentially perfect. The ability to precisely control the
arrangements of impurities and defects with respect to each other, and the
ability to integrate perfect inorganic and organic nanostructures, holds forth
the promise of a completely new generation of advanced composites.
Supplementary Homework
Reading:
• Engines of Creation (not required)

Please Note: Some of the text should be
categorized as Science fiction since it
violates some fundamental physical laws.
It still is very interesting.
