Comparison of some different ways used for approximate solution of kinetic equation and calculations of carrier mobility

Abstract

Consideration of different problems of physical kinetics shows that obtained non-equilibrium distribution function and following kinetic coefficients calculated are significantly dependent on choice of approach to approximate solution of kinetic equation. Therefore, in real practice any separate popular way of solution cannot be confidently considered as a reliable result. Here, several approaches are used, and the obtained different distribution functions and mobility have been compared.
