Kurzfassung englisch:
A finite-volume scheme for the stationary unipolar quantum drift-diffusion equations for semiconductors in
several space dimensions is analyzed. The model consists of a fourth-order elliptic equation for the electron
density, coupled to the Poisson equation for the electrostatic potential, with mixed Dirichlet-Neumann
boundary conditions. The numerical scheme is based on a Scharfetter-Gummel type reformulation of the
equations. The existence of a sequence of solutions to the discrete problem and its numerical convergence to
a solution to the continuous model are shown. Moreover, some numerical examples in two space dimensions
are presented.
