Abstract

We report the direct optical observation of confinement and transport of minority holes in a two dimensional electron gas. 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 ...
