Thermoelectric properties of (AgSbSe2)0,8(PbTe)0,2 solid solution		  pdf 

ABSTRACT

Temperature dependences of electrical conduction and thermal e.m.f. in the temperature interval 300-550K in (AgSbSe2)0,8(PbTe)0,2 solid solution are studied. In addition, X-ray structure and differential scanner calorimetric analyses are carried out, and its crystal structure and lattice parameters are determined. An endoeffect with maximum at T≈376,2K in the temperature interval T≈335-435K and also the strong decrease of electrical conduction value above T≈375K and the change of conduction type near T≈430K are observed.

Keywords: thermoelectric material, electrical conductivity, thermoelectric driving force, endothermic effect
