Abstract

An analysis is made of the collisions of electrons and holes with impurity atoms and excitons. Approximate formulas are given for the description of the contribution of these processes to the conductivity and collision frequency. A comparison is made with the experimental data for germanium at helium temperatures. The influence of the anisotropy and the role of the nonadditivity of the scattering mechanisms are examined. It is shown that the interaction of charges with excitons may increase the equilibrium free-charge density and thus influence the conductivity.
