Abstract:

The main objective of the Clemson DARPA project is to search for and achieve higher performance low temperature 100 K to 250 K thermoelectric materials than exist to date. Dr. Tritts group at Clemson University will perform synthesis and characterization of a number of low dimensional systems which show potential for use in thermoelectric applications. Initially Tritts group has been and will continue to pursue studies of the low-dimensional pentatelluride materials HfTe5 and ZrTe5. Tritts group will perform doping studies of the thermoelectric properties of these materials as well, which will include compounds such as Hf1-XZrXTe5. Subsequent doping studies on this family of compounds will include other substitutions, Hf1-XMXTe5-YZY, where M Zr, Ta, Nb, Ti etc. and Z S or Se. Tritt presented the preliminary results of the Hf1-XZrXTe5 study at the XVI International Conference on Thermoelectrics in Dresden. Other promising low dimensional materials will also begin to be investigated.
