English abstract:
A nite-volume scheme for the stationary unipolar quantum drift-di usion 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.
