Abstract

On the basis of a generalization- and a systematization of the few data on the fundamental parameters of electrons in ionic crystals, an analysis is carried out on the optimum concentration of nonequilibrium carriers, the magnitude of the applied electric field, and the excitation conditions when an object's electron conductivity is changed. Peculiarities, limitations, and some technical complications of the experimental investigation of electron conductivity of ionic crystals are described. It is demonstrated that, for crystals with a very wide gap (Eg > 10 eV), which are important in practical-terms., the most effective method for determining carrier parameters is to measure the conductivity induced by short x-ray pulses of low density.
