Abstract: We investigated the magnetotransport through high mobility InAs/GaSb antidot lattices with large antidot diameter at different temperatures and varying electron concentrations. In addition to pronounced low-field peaks already known from GaAs antidot lattices, we find an additional broad maximum at fields slightly above 2 T, which is associated with rosetta orbits surrounding one antidot. The results of a numerical analysis based on the classical Kubo formula using a hard-wall potential are in good agreement with experiment. At low temperatures we observe weak, nearly 1/B-periodic oscillations superimposed on this maximum, which may be due to quantized rosetta orbits. (C) 1998 Elsevier Science B.V. All rights reserved.
