Influence of inter-electron scattering on the form of non-equilibrium distribution function of band carriers

Abstract

Consideration of different problems of physical kinetics shows that non-equilibrium distribution function of band carriers and, consequently, kinetic coefficients significantly depend on the specific shape of bands and mutual interaction of carriers. The most impressive results are related with interband scattering of mobile particles belonging to many-valley systems. Especially essential process of e-e-interaction is peculiar for the so-called half-metals (wolfram, bismuth, molibden, indium and many others).
