Description

The transport properties of (AgSbTe2)0.9(PbTe)0.1, namely, the electrical conductivity and the Seebeck (S) and Hall (RH) coefficients, are studied in the temperature interval 80–560 K. An endothermic peak at 410 K is found by the differential scanning calorimetry (DSC). Sharp changes in the temperature dependences of the electrical conductivity and thermoelectric power in the region near 410 K are observed. The temperature dependence of Hall coefficient passes through maximum at ∼200 K and has negative sign. It is shown that, these peculiarities are due to the presence of the Ag2Te phase. The thermoelectric Z-factor has the maximum value of 2.7 × 10-3 K-1 at 400 K (author)
