Abstract

In previous investigations we have introduced a variety of new chalcogenide-based materials with promising properties for thermoelectric applications. The chalcogenide CsBi₄Te₆ was previously reported to have a high ZT product with a maximum value at 260K. In order to improve this value, a series of doped CsBi₄Te₆ samples has been synthesized. Current doping studies have been very encouraging, with one sample found to have a maximum power factor of 51.5 μW/cm·K² at 184 K. This paper reports on material characterization studies through the usual transport measurements to determine optimum doping concentration for various dopants.
