Abstract
We introduce small-angle scattering into the interpretation of the low-field magnetoresistance and the Weiss oscillations of a periodically modulated two-dimensional electron gas. Comparison between our experiments and a Monte Carlo simulation determines the small-angle scattering rate versus the carrier density and the periodic modulation of the carrier density.Keywords
