+- Science Magazine reports ZT=2.2, and other wonders.

Last week's issue of Science ( Feb. 6, 2004, Volume 303(5659),
http://www.sciencemag.org/) has no less than three articles on
thermoelectrics. The first (Majumdar, 2004) gives a nice introduction and
discusses some of the recent trends in thermoelectric materials R&D,
emphasizing nano-scale effects.

The second article (Lyeo, et al, 2004) describes a rather novel experimental
technique related to scanning tunneling microscopy. But rather than probing
the local tunneling currents this method probes the local thermal emf by
maintaining the sensing probe at a temperature different from the sample.
Since thermoelectric voltages are connected to local carrier concentrations,
this method provides a novel probe of carrier density with nanometer
resolution. This may well prove a handy technique, and not only for
thermoelectricians.

The third article (Hsu, et al, 2004) is a product of the prolific chemistry
investigations of Kanatzidis. Here they report an otherwise fairly ordinary
PbTe-based material which just happens to have ZT=2.2 at 800 K. The
material is cubic and prepared by what sounds like pretty conventional
methods. At last we have a high ZT value that should be fairly straight
forward for other groups to reproduce. Personally, I was impressed that
they took the radical step (by modern standards) of actually reporting error
bars on their measurements: 4% here, 10% there. If I recall my freshman
propagation of errors lecture correctly, their ZT values have an uncertainty
of about +- 24%. I can believe that.

As for their suggestion that "nanodots" observed in the sample may have
something to do with the high ZT values, I'll look forward to the systematic
studies demonstrating the correlation. Looks to me like just an unusually
good PbTe, but that's me. I prefer the old name for those "nanodots". We
used to call them "inclusions".

All in all, an impressive issue.

+- Report from MCALC IV - Cryocooler Meeting
by Daryl Treger

Cryocoolers Users and Suppliers Meet in San Diego for a Fourth Industry
Assessment Workshop - MCALC IV

A two-day industry meeting on Military and Commercial Applications for
Low-cost Cryocoolers (MCALC) was held in San Diego, CA on November 20th and
21st, 2003. The meeting was sponsored by Strategic Analysis, Inc.
(www.sainc.com) in cooperation with DARPA, the Army Night Vision Labs
(NVESD), and Dr. Martin Nisenoff of Nisenoff and Associates (retired NRL).
Attendees included representatives from the U.S. and foreign cooler vendors,
users, and integrators, with presentations discussing their cryocooler needs
and programs. The continuing objective of this workshop is to perform an
industry assessment on the current status of low cost, highly reliable
cryocoolers and to estimate the current and perceived needs of the cooled
electronic communities. Emphasis is focused on low cost cryocoolers
operating in the temperature ranges below 232 K (- 40 C) with attention to
the requirements of the user communities on reliability, efficiency,
temperature stability, EMI, vibration, audible noise, etc.

During the workshop, there was a series of presentations from the user
communities (such as IR cameras, cooling of semiconductor devices and chips,
cellular base stations, satellite applications, medical applications, and
high temperature superconductivity) outlining their projection of
cryocoolers needed for present and future generation of equipment, and
presentations from a variety of cryocooler vendors outlining what is
currently available. MCALC IV also had additional presentations from some
key low-temperature applications and cryocooler companies (down to 4K). The
twenty-three invited speaker presentations included twelve cryocooler
manufacturers, ten users, and one discussion of the Cryocooler Database
sponsored by the University of Twente. There was also exhibitor space
available for cryocoolers vendors to display their products, brochures and
technical data.

Of particular interest to the thermoelectrics community were presentations
from Clemson University and RTI, discussing the latest state-of-the-art in
cooling. Also of note is a presentation from INTEL, discussing the power
dissipation requirements on future generations of semiconductor devices;
this is an application area that thermoelectrics may have some solutions for
with respect to spot cooling.

The Proceedings from MCALC IV is now available on CD. To view the conference
agenda, to find out more information on the MCALC IV Conference, to express
interest in MCALC V, to have your name added to the MCALC contact list, or

International Academy of Refrigeration (IAR)
General Session of the International Academy of Refrigeration – 2004
by Lev Bulat

The General Session of the International Academy of Refrigeration – 2004 will
be held April 20-21, 2004 in St. Petersburg State University of
Refrigeration and Food Engineering, Russia. All members of the Section for
Alternative Methods of Refrigeration of the IAR are invited. On April 21 we
plan to organize the workshop for discussion about trends of thermoelectric
cooling and application.

The Session will focus on the future of refrigeration, air-conditioning,
cryogenics and food technologies. The election of new individual members of
the IAR will also occur at the Session. The deadline for individual member’s
Applications is March 19, 2004. The Applications can be sent by e-mail, by
fax or by regular mail. The Application Form and complete information about
the International Academy of Refrigeration and about the Section is
presented at http://www.zts.com/iar.

If you have any question about the organization of the Session contact please
me.

+- Another CalTech/JPL Thermoelectric Postdoc

[Note a CalTech/JPL postdoc postion was described in the last
ZTspam.20040114. This is a different position. - ed]

The California Institute of Technology (Caltech), Postdoctoral Scholars
Program at the Jet Propulsion Laboratory (JPL) invites applicants to apply
for a postdoctoral research position at JPL in the Analytical Chemistry and
Materials Development branch of the Mechanical Systems Engineering and
Research Division .

The research will assist in the development of novel sol-gel
synthesis processes to fabricate non-silicate-based aerogels that are
capable of withstanding exposure to high temperatures (>1000C) and volatile
metal vapors such as Ge, P, B and Sb. A separate, but closely related
project will seek to develop a methodology to characterize sublimation
suppression of these metal vapors.

Candidates should have a recent Ph.D. in materials science or
chemistry with a strong background in experimental research. The position
requires thorough familiarity with sol-gel chemistry, supercritical fluid
extraction and methods of characterizing aerogel, e.g. BET, FTiR, Raman,
TGA-DSC. The aerogel will primarily serve as a metal vapor sublimation
barrier, thus the applicant must posses experience with weight loss and
Knudsen Cell-like experiments. Excellent communication skills, the ability
to work independently, propose and lead small R&D projects is also desired.
The appointment is contingent upon evidence of completion of a Ph.D.

The annual starting salary for a recent Ph.D. is approximately
US$48,500 and can vary somewhat according to the applicant's qualifications.

Postdoctoral scholars positions are awarded for a one-year period.
Appointments may be renewed in one-year increments for a maximum addition of
two years. The appointments are expected to begin early in 2004.

Please send a letter describing your research interests, a curriculum
vitae, and a list of three references (with telephone numbers and postal and
e-mail addresses) to: Dr. Jeff Sakamoto
Jet Propulsion Laboratory, MS 277/207
4800 Oak Grove Dr.
Pasadena, CA 91109-8099 USA
E-mail: Jeff.S.Sakamoto@jpl.nasa.gov

Caltech and JPL are equal opportunity/affirmative action employers.
Women, minoritites, veterans, and disabled persons are encouraged to apply.
