Abstract

On the basis of investigations of the temperature and concentration dependences of kinetic coefficients (the Hall coefficientR, the electrical conductivity σ, and thermopower α0) in n-type Ag2Te, it is established that Ag atoms in Ag2Te create the shallow donor levels located at a distance of (0.002−7 × 10−5T) eV from the bottom of the conduction band. It is shown that silver telluride has n-type conductivity starting with the deficiency of Ag ≥ 0.01 at % in the stoichiometric composition, and it is practically impossible to achieve the stoichiometric composition in Ag2Te.
