My laboratory has developed novel procedures for the synthesis of
nanocrystalline semiconductors using biomolecular capping materials.
Processes for isolation of uniformly-sizes particles have also been
developed. We plan to use these materials, among other things, in
photo-degradation of organic contaminants and certain medical applications.

The Center for Nanotechnology was establish as part of the University
of Washington's Initiative fund awards for 1997, which emphasizes a
campus-wide interdisciplinary approach to intellectual and educational
paths, while strengthening undergraduate and graduate education,
extending the scope of research, and proving a new approach to
public service as one way of blazing a trail to the future.
The Center's main force is a marriage of physical, life, and engineering
sciences, all in which the University of Washington has broad strength.

Research into the properties of nanometer-scale single crystallites has
recently matured into a field that is both fundamental and wide-ranging,
although a major source of motivation arises from certain natural
phenomena and from technological questions concerning ultimate limits
on the miniaturization of solid-state device elements. As the smallest
recognizable solid-state structures, nanocrystals typically measure from 1
up to 10 nm in diameter, or 3 to 30 lattice planes in each dimension, and
are composed of from 102 up to 104 or 105 atomic or compound units.
The latter numbers represent the limit of atom-counting (circa one part in
105 is the current world's record), and this laboratory accordingly is
centered around specially designed mass spectrometers.
A central area of investigation concerns the equilibrium structures of small
crystallites and their thermodynamic stability; the specification of structure
encompasses lattice type, crystallite morphology (shape), and the surface
structure (including reconstructed or passivated forms). High-resolution
microscopy, performed at the best-resolution (atomic plane) limits in the
newly established Georgia Tech Center for High-Resolution Electron
Microscopy and elsewhere, is an essential resource for this laboratory.
Recent experimental findings and theoretical modelling have made clear
that high-symmetry, defect-free polyhedral structures can have unusual
structural and thermochemical stability, and these have become the focus
for intense exploration.
The electronic, optical and magnetic properties of nanocrystals are
modified from those of extended solids by the quantum size effects, which
arise from the discreteness of the energy level structure and finiteness of
the number of electrons or excitations within a band. These are also
under investigation in the laboratory by spectroscopic methods, both for
isolated particles and for those in arrays of weakly coupled equivalent
crystallites. These arrays constitute a novel material form with high
potential for unusual and useful properties.
A third area of research is concerned with the elementary steps in the
processing of nanometer-scale crystallites. Processing incorporates the
sequence: crystallite growth, annealing of defective structures, etching,
passivation, and separation of completely passivated crystallites
according to size. A major effort of the laboratory over the past decade
has been the development of universal instruments for carrying out and
measuring these steps. The solid-state systems investigated are chosen
largely for their tractability, both experimental and for modelling; these
have included ionic solids (such as NaF), binary semiconductors (PbS),
noble metals (Au), magnetic metal oxides, and ordered carbon structures.
Theoretical modelling, or simulations, are critical in establishing ideas
and models for the structural, processing, and other properties of
nanocrystals; supercomputer-based simulations are carried out in
association with the Georgia Tech Center for Computational Materials
Science.

Zyvex headquarters
Zyvex was founded in April 1997 by Jim Von Ehr, and is based in Richardson Texas. Click here
for a map.
Zyvex' goal is to build one of the key pieces of molecular nanotechnology; the assembler. The
term assembler is fuzzy
and should be more clearly defined. In our context, nanomanufacturing plant might be a better
definition. This is a system
of unspecified size (possibly quite large), capable of manufacturing bulk materials or arbitrary
structures with atomic
precision, getting nearly every atom in the desired place. It probably performs its task by doing
mechanochemistry, which
is a chemical reaction helped over its normal reaction barriers by mechanical force. Another
possibility is positional
electrochemistry, which overcomes the reaction barriers by careful use of electric charge.
Examining some steps towards this goal, we can observe that a semiconductor manufacturing
plant manufactures
arbitrarily complex structures (with restricted chemical compounds), but lacks atomic precision.
Bacteria are atomically
precise, self-replicating manufacturing plants which manufacture substances with atomic
precision. They can even be
genetically engineered to manufacture certain novel compounds, but cannot make arbitrary
structures. The Zyvex
assembler differs from both in that it operates on some atomically precise molecular building
blocks to build precise
structures of arbitrary complexity, as specified by a CAD/CAM program.
This first assembler can be a crude device; its purpose is to show that molecular nanotechnology
is feasible, and to start
the field on a Moore's law type of learning curve. Moore's "law" is an observation by Gordon
Moore of Intel that because
we learn how to improve the density of silicon circuits in each hardware generation, the number of
transistors in a
microprocessor can double every 18 months. A related concept is the semiconductor "learning
curve", where the cost of
making something goes down as the manufacturing process matures and process variables are
more carefully controlled.
In order to get on the desired type of learning curve, we must make a product of commercial
value that cannot be
economically made in another way. Additionally, the manufacturing system must be capable of
being improved by the
products it manufactures. A semiconductor manufacturing plant cannot manufacture itself, hence
the cost of a
semiconductor production line goes up with each generation, and is nearly unaffordable A welldesigned nanotechnology
manufacturing plant will not suffer from this problem.
Zyvex is a developmental engineering company. It is currently funded at a level sufficient to both
do its own research and
sponsor research grants to universities doing research in complementary fields. With a 5-10 year
time horizon for its first
revenue, it is one of those rare startups that need not be focused on near-term profits.
Self-imposed pressure to market intermediate advancements is likely to be strong, and it may be
desirable to spin off such
products either as a separate company or via licensing.
Many people have inquired about investing in Zyvex. We do not need any outside funds at this
time. See the Investment
page for more information.
Zyvex has several staff positions open. See the Hiring page for a list of positions to be filled.
Zyvex has a mailing list for updated information on the company. Look here for details.
