2.3 Boltzmann's Transport Equation

The general approach to obtain the non-equilibrium distribution function in the semiclassical approximation is based on the Boltzmann kinetic equation. The kinetic equation gives the microscopic description of the evolution process of the electron system. This description is valid at time intervals longer than the interaction duration and at distances longer than the size of the interaction domain.
