Part 1: Existence and uniqueness of solutions %D 2001 %@ 1468-1218 %U https://hdl.handle.net/20.500.14352/57337 %X This paper is about the drift-diffusion equations for semiconductors. Existence and uniqueness of weak solutions are obtained. The existence is proved by using the regularization technique. The proof of the uniqueness is interesting. %~
