Microscopic Picture of the Quantum Hall Effect




Hall resistance of two-dimensional electron system
as function of magnetic field shows well-quantized

Scanning probe microscopy investigating quantum Hall samples has been performed in our group for many years and has led to a microscopic picture for the current distribution in quantum Hall samples which contradicts the current-carrying edge-state model.
