Abstract

Several new materials in the A/sub 2/Bi/sub 8/Se/sub 13/, (A=K, Rb, Cs), HoNiSb, Ba/Ge/B (B=In, Sn), and AgPbBiQ/sub 3/ (Q=S, Se, Te) systems have shown promising characteristics for thermoelectric applications. To accommodate the large number of samples required for doping and alloying studies, a new measurement system has been designed with a high sample throughput. A second system is then utilized for complete characterization of the most promising samples. This paper presents a description of the systems and measurement techniques involved, with preliminary data on some of the above mentioned compounds.
