Resonance Scattering of Electrons in Ag2Te

“…2). The course of σ(T ), R(T ) and α 0 (T ) at the concentration of N a ≈ 6.25×10 16 cm −3 is analyzed [2].…”

“…By solving (2) electron concentration in the temperature interval under study is determined. It is found in paper [3] that valence zone is parabolic and then p is determined according to [2]:…”

“…Calculation of temperature relationship U n (T ) and U p (T ) in a sample of N a = 4.2 × 10 16 cm −3 in case of charge carrier scattering on ionic centres to the procedure in [2]; electron concentration was calculated from the formula…”

“…It is related in the paper [1] that resonance scattering of electrons on acceptor impurities does not take place in n-Ag 2 Te at the donor concentration of N d ≥ 6.2 × 10 16 cm −3 . In the paper [2] electrical and thermoelectrical properties of p-Ag 2 The present research is dedicated to the study of electrical and thermoelectrical properties of p-Ag 2 Te in samples with the acceptor concentration of N a ≤ 7.8 × 10 16 cm −3 .…”

“…In the paper [2] electrical and thermoelectrical properties of p-Ag 2 The present research is dedicated to the study of electrical and thermoelectrical properties of p-Ag 2 Te in samples with the acceptor concentration of N a ≤ 7.8 × 10 16 cm −3 . In all the samples of p-Ag 2 Te two peculiarities are observed on temperature relationship of electric conduction σ(T ) in the 4.2 ÷ 200 K temperature range: a plateau at T < 40 K and a minimum at T ≈ 65 K (Fig.…”
