Abstract

The synthesis and study the structure and thermoelectric properties of silver doped of lead telluride with impurity concentration of 0.3, 0.5, 1.0 at.%. Established that in the samples PbTe: Ag with impurity concentration
> 0.5 at. % Ag present phase pure lead, due to reaching the solubility of impurities. The influence of temperature of annealing on Seebeck coefficient, thermal conductivity and specific conductivity was identified.
