摘要：

We report transverse magnetic focusing experiments on two-dimensional hole systems confined in square and triangular quantum wells grown on (311)A GaAs substrates. The focusing barriers are oriented along different crystallographic directions and allow us to derive the constant energy contours in k-space. The results indicate a nearly elliptical shape for these contours which we interpret in light of a lateral surface superlattice induced by corrugations at the heterojunction.
