On some numerical problems in semiconductor device simulation

Part of the Lecture Notes in Mathematics book series (LNM,volume 1460)

Abstract

We recall in the introduction the main features of the drift-diffusion model for semiconductor devices, pointing out its physical meaning, its possible derivation, and its limits. Then, in Section 2, we present a mixed finite element method for the discretization of this model. Finally, using asymptotic analysis techniques, we compare the qualitative behaviour of the mixed method with other methods (classical conforming Galerking method and harmonic average methods). This asymptotic analysis provides some indication of the advantages of the mixed method.

Keywords

  • Mixed Method
  • Mixed Finite Element Method
  • Order Elliptic Problem
  • Harmonic Average
  • Mixed Approximation

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
