The Initial Time Layer Problem and the Quasineutral Limit in the Semiconductor Drift–Diffusion Model
The classical time-dependent drift-diffusion model for semiconductors is considered for small scaled Debye length (which is a singular perturbation parameter multiplying the Laplace operator in the Poisson equation). The corresponding limit is carried out on both the dielectric relaxation time scale and the diffusion time scale. The latter is a quasineutral limit and the former can be interpret...
متن کاملThe Initial Time Layer Problem andthe
The limit of vanishing Debye length in a nonlinear bipolar drift diiusion model for semiconductors is studied. The limit is performed on both the initial time layer and the original time scale. In both cases the limiting problems are identiied. A main tool in the analysis are entropy methods.
