Resonance Scattering of Electrons in Ag₂Te

Abstract

The temperature dependences of electric conductivity σ, the Hall coefficient R of p-Ag 2 Te in 4.2-200 K temperature interval for acceptor concentration N a ≤ 6 × 10 16 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 N a decrease. It was shown that the part resonance scattering of electrons in minimum of σ(T ) and maximum of |α n (T )| region is 16-18%.
