Abstract:

This paper is devoted to the long time behavior for the Drift-diffusion semi-
conductor equations. It is proved that the dynamical system has a compact, connected
and maximal attractor when the mobilities are constants and generation-recombination
term is the Auger model; as well as the semigroup S(t) defined by the solutions map is
differential. Moreover the upper bound of Hausdorff dimension for the attractor is given.

Key words: Drift-diffusion model, auger term, attractor, Housdorff dimensions
