Title: Nonlinear Multigrid Applied to a One-Dimensional Stationary Semiconductor Model
Abstract: The nonlinear multigrid method is applied to a transistor problem in one dimension. A weak spot in the linearization of the well-known Scharfetter–Gummel discretization scheme is reported. Further, it is shown that both the residual transfer and the solution transfer from a fine to a coarse grid need special requirements due to the rapidly varying problem coefficients. Some modifications are proposed which make the multigrid algorithm perform well for the hard example problem.
