Scanning gate experiments on a two-dimensional electron gas in the regime of the classical Hall effect are presented. The Hall resistance is recorded while tuning the local potential by applying a voltage to the metallic tip of a scanning force microscope. In diffusive samples and at zero magnetic field an intriguing Hall resistance pattern arises that is attributed to tip-induced inhomogeneous current flow. Measurements at small, i.e., nonquantizing, magnetic fields reveal an additional Hall… Expand

The microscopic nature of localization in the quantum Hall effect
The experiments suggest a unified picture of localization in which the single-particle model is valid only in the limit of strong disorder, and it is concluded that the quantum Hall effect has a greater diversity of regimes and phase transitions than predicted by thesingle-particles framework.
