Abstract

Periodic antidot arrays imposed upon two-dimensional hole systems (2DHSs) display a striking dependence of the positive low-field magnetoresistance on the in-plane crystallographic orientation of the superlattice. An enhanced positive magnetoresistance can be ascribed to the 2DHSs non-circular Fermi surface which stabilizes chaotic trajectories for specific crystallographic directions. The effect ...
