Abstract
Theory of electron-polar optical single phonon field-induced tunnel scattering under the influence of an electric field is considered. It is assumed that the non-degenerate polar semiconductor has a spherical parabolic band structure. In low-field regime, an expression for the scattering time is obtained. Dependence of the scattering time (the scattering rate) on the electron energy is analyzed. The results of corresponding numerical computations for an n-GaAs at 300 K are presented. It is established that there is no fracture on the curve of electron scattering time (scattering rate) dependence on the electron energy.
