Anomalies in nonlinear transport of two-dimensional electron gas

ORAL

Abstract

When a dc current is passed through a high-mobility two-dimensional electron system subject to a weak magnetic field, its differential resistivity exhibits periodic oscillations as a function of applied current. The waveform of these oscillations, known as Hall field-induced resistance oscillations, is well established both experimentally and theoretically. In this talk we will present experimental data which show dramatic deviations of the oscillation waveform from the theoretically predicted.
