Abstract
GaAs/AlGaAs heterostructures systematically doped with additional Be or Si impurities near the two-dimensional electron gas show distinct shifts of the quantum Hall plateaus and of the minima in the longitudinal resistivity xx relative to the expected values of the Landau-level filling factor. A quantum Hall plateau xy=h/e2 which does not cross the classical straight line xy0=B/nse is observed. The results are explained by a microscopic transport calculation emphasizing non-Born scattering of electrons by individual impurities.
