Kinetik Properties of (AgSbТe2)0.8(PbTe)0.2

The kinetic properties of the compound (AgSbTe2)0.8(PbTe)0.2 were investigated. Measurements of electrical conductivity, Seebeck coefficient, and Hall coefficient were conducted on the 80–550 K temperature intervals. Some features on the temperature dependencies of the kinetic coefficients were observed. It was shown that the presence of the Ag2Te phase reduce to Hall coefficient maximum at 200 K and its negative sign. It was estimated the effective mass $$m_{{\text{d}}}^{*}$$ = 0.46me according to experimentally measured Seebeck and Hall effect data.
