A quantum-mechanical model based on a Green's function approach has been used to calculate the transmission probability of electrons traversing a two-dimensional electron gas injected and detected via mode-selective quantum point contacts. Two-dimensional scattering potentials, backscattering, and temperature effects were included in order to compare the calculated results with experimentally observed interference patterns. The results yield information about the distribution, size, and the energetic height of the scattering potentials.
