Abstract

We discuss the behavior of junctions between two coplanar 2D electron gases with different densities in a perpendicular applied magnetic field. The presence of energy gaps in the density of states caused by Landau level quantization and spin splitting leads to behavior in these junctions qualitatively similar to what is observed in a semiconductor p-n junction. We will emphasize aspects of these junctions where the role of electron-electron interactions are important in understanding their properties.
