ABSTRACT

The temperature dependences of electrical conductivity and thermoelectric power of AgSbSe2 and (AgSbSe2)0.9(PbTe)0.1 solid solution were investigated in the 80-350K temperature range. The value of electrical conductivity of PbTe added composition decreased compared to AgSbSe2 and the inversion of the sign of thermoelectric power (np) was observed. The effective mass of the studied composition has been calculated. It has been determined that the value of effective mass in (AgSbSe2)0.9(PbTe)0.1 solid solution increased compared to AgSbSe2.

Keywords: thermoelectric material, electrical conductivity, thermoelectric driving force, effective mass.
