PREFACE

Symposium Z, "Thermoelectric Materials 2000—The Next Generation Materials forSmall-Scale Refrigeration and Power Generation Applications," held April 24-27 at the 2000MRS Spring Meeting in San Francisco, California, was the fourth in a series of MRS symposiawhich are specifically related to research in new thermoelectric materials [see MRS SymposiumProceedings Vol. 234 (1991), Vol. 478 (1997) and Vol. 545 (1999).] At this Meeting therewere over 60 contributed oral presentations, 11 invited talks and 22 poster presentations.Some of the highlights of this Meeting were results presented by Ted Harmon of MIT LincolnLabs on quantum dot nanostructures of PbTe materials. These materials appear to exhibit asubstantial improvement over their bulk counterparts with a ZT ~ 2. The Kanatzidis group atMichigan State University presented an update on the CsBi4Te6 material since theirannouncement in Science Vol. 287, pp. 1024-7 (2000). In addition, George Nolas of MarlowIndustries and Brian Sales of Oak Ridge National Laboratory presented results on a Yb partiallyfilled skutterudite with ZT > 1 at 300 °C. There were also many interesting results in theclathrates, skutterudites, quasicrystals and novel chalcogenide materials systems as well as inIII-V compounds for thermionic refrigeration. As in past symposia, both bulk and thin filmthermoelectric materials research was well represented. Thermoelectric materials are used in awide variety of applications related to small-scale solid state refrigeration or power generation.

Over the past thirty years, alloys based on the Bi2Te3 compounds (refrigeration) andSii_xGex compounds (power generation) have been extensively studied and optimized for theiruse as thermoelectric materials. Thermoelectric cooling is an environmentally "friendly"method of small-scale cooling in specific applications such as cooling computer chips, smallbeverage coolers, cooling laser diodes and infrared detectors. Another very importantapplication of thermoelectric materials is in power generation for deep space probes such as inthe Voyager and Cassini missions. Despite the extensive investigation of these traditionalthermoelectric materials, there is still substantial room for improvement, and thus, entirelynew classes of compounds will have to be investigated. Therefore, the focus of this symposiumcenters around the development of the next generation materials for small-scale refrigerationand power generation applications.

The essence of a good thermoelectric is given by the determination of the material'sdimensionless figure of merit, ZT =(a2o / X)T, where a is the Seebeck coefficient, a is theelectrical conductivity, and X is the total thermal conductivity. The thermal conductivityconsists of two parts, the electronic and the lattice thermal conductivity. Many of the paperspresented in this proceedings revolve around either maximizing the numerator of ZT called thepower factor, PF = a 2 cT, or by minimizing the lattice thermal conductivity. As previouslydescribed by Glen Slack, a promising thermoelectric material should possess the thermalproperties of a glass and the electronic properties of a crystal, i.e. a phonon-glass and electron-crystal (PGEC). This theme is quite prevalent in the many papers presented in this volume.The best thermoelectric materials have a value of ZT ~ 1, which has been an upper limit formore than 30 years, yet no theoretical or thermodynamic reason exists for why it cannot belarger. We believe that the future advances in thermoelectric applications will come throughresearch in new materials, and that is why we have focused the symposium on research in newmaterials, instead of further optimization of established materials. There are currently manynew methods of materials synthesis and much more rapid characterization of thermoelectricmaterials than were available 20 to 30 years ago. Many new researchers and new ideas areappearing in this field, which gives us much anticipation about future advances. It is the hopeof the organizers of this symposium that these proceedings will provide a benchmark for thecurrent state in the field of new thermoelectric materials at this time.

At the end of the symposium, there was a special session where program managers WendyFuller-Mora (NSF), Valarie Browning (DARPA), Jack Rowe (ARO), and Jerry Smith (DOE)discussed potential opportunities for thermoelectric research. This was followed by a short

question and answer period. One distinction at this symposium was the large number ofgraduate student presentations, numbering over twenty. The symposium organizers were ableto give three graduate student presentation awards and a poster award. The student awards forbest papers and presentations were: Ganesh Ramachandran, Arizona State University (who alsowon one of the general MRS best paper awards), Marc Ulrich, Auburn University, and MelissaLane, Northwestern University. The best student poster award went to Nishant Ghelani ofMichigan State University. These awards were enabled by the support of High-Z Corporation,Marlow Industries, MMR Technologies and MRS. The organizers appreciate and acknowledgethe support of these sponsors. Much of the research and the results which are presented in thisvolume were supported by DARPA, the Office of Naval Research and the Army ResearchOffice. Their financial support is greatly appreciated and acknowledged. We also acknowledgethe assistance of Marian Littleton and Lori McGowan of Clemson University in all phases ofassistance concerning the symposium organization and subsequent proceedings. Their diligenceand hard work both before and after the symposium allowed for the timely progress of themanuscripts and proceedings in preparation for publication of this volume.
