Abstract

In this paper we consider two models derived from the semiconductor Boltzmann equation by using the spherical harmonic expansion method. The first model contains only two terms of the expansion, the second also the third term. We look for space-homogeneous solutions to two Cauchy problems. Numerical results are found using a simple difference scheme and a comparison between the two models is shown.
