Abstract
In spatially resolved magneto-optical experiments we observe hole confinement at the edge of a two-dimensional electron gas and hole transport in edge channels. In a theoretical analysis we show that a repulsive edge potential for holes at the boundary of a two-dimensional electron gas is caused by a polaron effect.
