Paper Title:
Electrical Properties of P-Type Thermoelectric AgxBi0.5Sb1.5-xTe3 (x=0.05~0.4) Alloys Prepared by Spark Plasma Sintering
  Abstract

Thermoelectric Ag-Bi-Sb-Te alloys with the general formula AgxBi0.5Sb1.5-xTe3 (x =0.05∼0.4) were prepared by spark plasma sintering and their electrical properties were examined. The alloys exhibit large electrical conductivities in the whole temperature range, which are approximate 11.0 and 3.5 times those of pseudo-binary Bi0.5Sb1.5Te3 alloy at room temperature and 558K, respectively. The highest power factor value of 1.80×10-3 (W.K-2.m-1) is obtained for the material (x = 0.1) at the temperature of 412K, being about 2.4 times that of pseudo-binary alloy Bi0.5Sb1.5Te3 at the corresponding temperature.
