Dr Li Chen Department of Mathematical Sciences Tsinghua University, Beijing, 100084, P.R.China Time and Place: 3:30 p.m., Friday, April 04, 2008, Allen 14 Title: "Quantum Drift-Diffusion Model in Semiconductor Simulation" Abstract: In this talk I will first give a brief introduction to the mathematical models in semiconductor simulation including classical and quantum models, microscopic and macroscopic models. Then I will switch to one of the macroscopic quantum models, the so called QDD model. We will show a series of results obtained recently, including the existence, semiclassical limit and long-time behavior of weak solutions to this kind of model. Our methods are based on semi-discretization in time for the approximation scheme and entropy estimates for compactness argument. The results on QDD model are joint works with X. Chen and Q. Ju.
