Abstract
We present a numerical Wigner function model for the simulation of mes oscopic semiconductor devices. An exact non-local formulation of the t ransport equation in the Wigner presentation and its discretization fo r numerical calculation are discussed. The capability of the developed Wigner simulator is demonstrated by applying it to a resonant tunneli ng diode where quantum interference effects are important.
