Electron scattering by acceptor centers in p-[Ag.sub.2]Te at low temperatures

Resonant electron scattering in p-[Ag.sub.2]Te at acceptor concentrations Na < 4.2 x [10.sup.16] [cm.sup.-3] has been observed in the temperature range of 50-80 K.

Description
Summary:Resonant electron scattering in p-[Ag.sub.2]Te at acceptor concentrations Na < 4.2 x [10.sup.16] [cm.sup.-3] has been observed in the temperature range of 50-80 K. The contribution of the resonant scattering to the temperature dependences of the conductivity [sigma](7) and thermopower [[alpha].sub.0](T) has been calculated. It is shown that this contribution exceeds that of charge carrier scattering by acoustic phonons. DOI: 10.1134/S106378261-8-87
