RT Journal Article T1 On a quasilinear degenerate system arising in semiconductors theory. Part 1: Existence and uniqueness of solutions A1 Díaz Díaz, Jesús Ildefonso A1 Galiano, Gonzalo A1 Jungel, Ansgar AB 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. PB Pergamon Elsevier Science Ltd.
