| Abstract | Measurements were made of the breakdown of the quantum Hall effect in GaAs/AlxGa1-xAs heterostructures with narrow constrictions (1 m). Structures were observed in both field sweeps and current sweeps. A simple model provides evidence that the origin of these structures is an inhomogeneity size effect which occurs when the length scale of the inhomogeneity becomes comparable with the sample width. The consequences of these inhomogeneities for critical current measurements are discussed. © 1989 The American Physical Society. |
