Thermoelectric properties of p-type (AgSbTe2)x(Pb0.5Sn0.5Te)1 − x (x = 0.05, 0.09, 0.2)

Polycrystalline-sintered samples of p-type (AgSbTe2)x(Pb0.5Sn0.5Te)1 − x (x = 0.05, 0.09, 0.2) were prepared from Ag2Te, PbTe, SnTe and Sb2Te3 by a solid-state reaction followed by hot pressing. The electrical resistivity, Seebeck coefficient and thermal conductivity were measured from room temperature to about 700 K. The effect of concentration in (AgSbTe2)x(Pb0.5Sn0.5Te)1 − x on their thermoelectric properties was studied.
