Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips

We use dynamic scanning capacitance microscopy to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime. This method gives access to the complex local conductance, G _ts , between a sharp metallic tip s...
