Abstract

We report the observation of discontinuities in the dV/dI characteristics of high-mobility two-dimensional (2D) electron systems in GaAs/AlxGa1-xAs heterostructures at very low Landau-level filling factors. We discuss a model of inhomogeneous current transport that is able to account for many of the observations independent of the 2D electron state.
