| The temperature dependences of electric conductivity σ, the Hall coefficient R of p-Ag2Te in 4.2-200 K temperature interval for acceptor concentration Na ≤ 6 × 1016 cm-3 were investigated. The minimum σ(T) was observed for all samples in ≈50÷80 K temperature interval. It was observed that the depth of minimum is increased with Na decrease. It was shown that the part resonance scattering of electrons in minimum of σ(T) and maximum of |αn (T)| region is 16-18%. |
