A triangular mixed finite element method for the stationary semiconductor device equations. (English) Zbl 0732.65114
The authors present a triangular finite element method for the stationary semiconductor device equations. This method can be regarded as an extension to two dimensions of the one-dimensional Scharfetter-Gummel technique. Existence, uniqueness and stability of the approximate solution are proved for an arbitrary triangular mesh and some additional corresponding mathematical details are discussed.
