Search for Lower Temperature(T-100K) Thermoelectric Materials in the Pentatelluride System and other Low Dimensional Systems
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. Tritt's 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 Tritt's group has been and will continue to pursue studies of the low-dimensional pentatelluride materials: HfTe5 and ZrTe5. Tritt's 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.
