    The Peculiarities of the Electrical and Thermo Electrical Properties of P-Type Ag2te
    (1999) Demirel, A.I.; Aliev, S.A.; Aliev, F.F.; Guseynov, F.Z.; Orak, S.
    The electrical and thermoelectrical properties of p-type Ag2Te have been investigated. Various peculiarities were observed: the minimum (at T≈65 K) and maximum (at T≈200 K) on the temperature dependence of conductivity σ(T); the weak dependence of Hall coefficient R(T) (in 200-300 K range) and the maximum (at T≈100 K and 250 K) on the temperature dependence of thermal power α0(T). The investigation results were interpreted by two-bands model. It is shown that mentioned peculiarities have been stimulated by the narrow gap of Ag2Te and its temperature dependence.
