Nonlinear transport in very high Landau levels of a high mobility quantum Hall systems

ORAL

Abstract

When a dc current is passed through a high-mobility two-dimensional electron system its differential resistivity exhibits oscillations with the applied magnetic field. The minima of these oscillations can extend all the way to zero leading to states with zero-differential resistance. This talk will discuss our recent experiments studying the evolution of the differential resistivity with temperature and with perpendicular and in-plane magnetic fields.
