Abstract
When considering the one dimensional semiconductor device equations, the condition number turns out to be so large that a numeric solution of the equation is meaningless. Applying singular perturbation methods to the linearized model the solution can be separated into two parts: One, which is very sensitive to perturbations, and one, which is robust against perturbations of the equations.
