This is one of several files containing lists of web-based resources for use in
connection with my graduate courses, web-based articles and talks. If you have items
you would like me to add, please email me. However, I am aiming to be exemplary rather
than comprehensive, so please don't be offended if I leave material out.

using AES, SAM and related techniques
- All AES/SAM analyses use an energy analyzer, which can be obtained from one
of several companies. One such is the
Concentric Hemispherical Analyzer (CHA)
from VSW in the UK which we have used in Arizona.
- Many Universities have centralized their surface analysis facilities,to maximize
accessibility and throughput, as for example the
Center for Microanalysis of Materials
at the University of Illinois (UIUC), which includes AES and SAM. Several Universities
have set up combined academic/ commercial units, such as Bristol University's
Interface Analysis Centre or Loughborough
Characterisation Centre in the UK.
- Industrial surface analyical laboratories and consultancies have grown substantially
over the past decade. The best known in the USA is undoubtedly
Charles Evans and Associates which now has
in addition East coast,
Midwest and two Asian operations,
seemingly swallowing up other firms, such as Physical Electronics Inc(PHI) and
Surface Science Laboratories
en route. A 1995 series of
AES was prepared by
Ron Fleming of the then C.A. Evans, Inc. in association with NSF, which includes some spectra
and nice graphics. Some other links are available on this site.
- Explanations of the terminology and acronyms of surface analysis can be found at
various society and commercial sites. Check out the comprehensive
list of acronyms, maintained by the
Surface Analysis Forum and/or the
Handbook of Analytic Methods
maintained by Materials Evaluation and Engineering Inc, which includes
AES and SAM.
- The National laboratories (e.g. NIST and NPL) have databases on particular topics.
For example, NIST now has three databases available for applications
in AES and XPS. Version 3.0 of their
XPS database (SRD 20) is available
for online access and is free. Version 2.0 of the
Electron Elastic-Scattering Cross-Section Database (SRD 64) was released in
April, 2000, and Version 1.0 of the Electron Inelastic-Mean-Free-Path
Database (SRD 71) in September, 1999; an enhanced version of the latter
database (Version 1.1) has been released more recently. The latter two databases
are available without charge on request to
Links to Nano-fabrication groups in Materials science
- One of the groups producing spectacular images is the
IBM Almaden Lab in California, with STM
pictures of the
Fe/Cu quantum corral.
This is just one example of the ability of probe microscopies to manipulate atoms on
surfaces. Several of the
STM groups listed on this site are also involved in this effort.
- There is however, even more interest in techniques which can assemble
patterns by parallel processing, and several efforts are underway, e.g. at the
Nanofabrication center at Cornell University,
but the name has recently been changed to the Cornell NanoScale Facility (CNF)
These and other activities now come under the general heading of Nanoscience and
Nanotechnology, which are featured on these pages as
Nanotechnology is everywhere!
- Conferences on related topics have sprouted everywhere. In 2003, you can catch up
with the CNF at the
Annual Meeting & Career Fair
in Ithaca, New York, in September. The Gordon Research Conference on
the Chemistry and Physics of
in New Hampshire in July, 2000, and this series was continued in
2002; it is scheduled for
2004 (July 18-23).
In 2001 you could have tried
Nano-Physics & Bio-Electronics - A new Odyssey held at the Max Planck
Institute for the Physics of Complex Systems in August, and/or
the NanoBioTech Congress
in Muenster, Germany, in September 2002 and 2003. These titles are going to drive us
all crazy, sooner rather than later.
- Several firms, including Symyx are
Combinatorial materials discovery, a
group of techniques designed to find optimum compositions of ternary or quaternary
thin film materials via parallel processing of addressable micro-arrays. One can follow
the progress of these firms, and their continuing need for venture capital, in
the financial press. This one is growing fast, and has some heavyweight scientists
on board; but the transition to a regular business is a rocky road, and there are
bound to be some casualties.
Links to Micro-array technology groups in Biochemistry
- An area which links microscopy and microanalysis in biochemistry is the fast
developing field of high precision arrayer machines. The
Pat Brown group at Stanford
first demonstrated the biochemical potential of these instruments, and has made
on the web.
- There are now many competing academic/medical/goverment lab groups, including the
University of Pennsylvania and
Lawrence Livermore Lab, all interested in
gene-sequencing and the
Human genome project. In 2000,
decoded the Drosophila genome
and planned to beat the publicly funded genome guys to the post on the
Human genome too. Read about it in the March 24th 2000 issue of
Correction! They did so plan until they patched up their differences, and made
a joint statement in the summer of 2000. Science by Press Release. Now that a huge
wall chart (February 16, 2001) is free online, has been given out to all
subscribers to Science, and I have seen my friends put it up on their lab walls,
I guess we now have to figure out a) whether it is correct; b) whether it is general,
or just applies to you know who, and/or c) what it all means.
This story will run and run.
- Instrument companies,
such as Affymetrix and
manufacture and improve robotic
microarray systems for a very competitive marketplace.
