Abstract
The conductivity σ, Hall coefficient R, and thermoelectric power α0 of p-Ag2Te were studied in the temperature range of 300–550 K. Inconsistency between the signs of R and α0 was observed at 420–550 K. These results are interpreted within the two-phase model with spherical constant energy surfaces. It is established that the inconsistency between the R and α0 signs is due to the emergence of the scattering mechanisms with the parameters r 0ac , r 00, and r 0d an increase of about 50% in the ratio of the effective electron and hole masses as a result of the transition α → β.
