Abstract
We study a time-dependent as well as a stationary
drift-diffusion-Poisson system for semiconductors. Global existence
and uniqueness of weak solution of the time-dependent problem are
proven and we also prove the existence and uniqueness of the steady
state. Finally, we discuss the large time asymptotics of the
time-dependent problem. This is a joint work with Prof. P. Markowich
and Prof. S. Zheng.
