Abstract
A model for the simulation of the interference patterns of an electron beam in a 2DEG in the presence of a perpendicular magnetic field is presented. The model is based on the Green function method and includes a realistic description of the scattering potential leading to electron interference effects in the 2DEG. Detailed information about distribution, strength and the size of the scattering potential are obtained from the simulation of the experimentally observed interference patterns. The results confirm theoretical assumptions about density-fluctuation correlations in a 2DEG.
