Closure relations for the production terms of the balance equations describing the motion of electrons in semiconductors are obtained by using the distribution function given, according to [1], by the maximum entropy principle in the case of the Kane dispersion relation for the energy band. Scatterings of electrons with non polar optical phonons (both for intervalley and intravalley interactions), acoustic phonons and impurities are considered. Applications to bulk silicon are presented. In particular the overshoot and saturation effects are described with good accuracy.

Abstract
Closure relations for the production terms of the balance equations describing the motion of electrons in semiconductors are obtained by using the distribution function given, according to [1], by the maximum entropy principle in the case of the Kane dispersion relation for the energy band. Scatterings of electrons with non polar optical phonons (both for intervalley and intravalley interactions), acoustic phonons and impurities are considered. Applications to bulk silicon are presented. In particular the overshoot and saturation effects are described with good accuracy.File in questo prodotto:
