On the Theory of Galvanomagnetic Phenomena in Strong Electric Fields

Abstract

Some galvanomagnetic effects are calculated for electric fields which are sufficiently high to give quadrac tideviations from Ohm's law. The calculations are carried out awiiming nonparabolicity of the energy band. Acoustic mode scattcring, and polar and nonpolar optical mode scattering are included in the analysis. Kanc's model of the nonparabolic band is used in the final result. In the case of a quadratic deviation from Ohm's law the isotropic function S is given [3] s = fo -!-s,, E, E, t

Galvanomagnetic and recombination effects in semiconductors in a strong electric field

“…[ 181, [39], [40]) devoted to the theoretical study of galvanomagnetic phenomena in a strong electric field. In [IS] and [39] the electron temperature approximation was used.…”

“…In [IS] and [39] the electron temperature approximation was used. I n [40] calculations were restricted to the cases of acoustical and optical scattering, but allowapce was made for the non-parabolicity of the dispersion relation using Kane's model [41].…”
