Title:
KINETIC THEORY OF IMPACT IONIZATION
IN MANY-VALLEY SEMICONDUCTORS
AND ALKALI HALIDE CRYSTALS
Authors:
V.A. Chuenkov.
Abstract:
The impact ionization is studied in detail in anisotropic many-valley semiconductors (Ge, Si, GaAs) with account of their real band structure, effective mass anisotropy, and redistribution of elecrons (holes) among valleys. Analytic expressions describing the dependence of impact ionization coefficients for electrons and holes on the electric field, temperature, and parameters characterizing the physical properties of semiconductors are derived. The critical electric fields Ec are calculated for which the electric breakdown of semiconductors and dielectrics occurs; the temperature dependence of Ec is obtained.
