Distribution of the quantized Hall potential in GaAs-AlxGa1-xAs heterostructures


Journal Article

We report measurements of the Hall potential distribution in the interior of the two-dimensional electron gas in GaAs-AlxGa1-xAs heterostructures. In the quantized Hall regime, our data provide direct evidence for the existence of extended states in the bulk of a two-dimensional system. Bunching of the potential distribution is observed as a function of the quantizing magnetic field and is attributed to the presence of density gradients as the dominant macroscopic inhomogeneities. © 1985 The American Physical Society.
