Abstract
We present a theoretical investigation of the magnetotransport in finite antidot lattices. We have calculated the magnetoconductance, which shows slow and rapid oscillations. To interpret the rapid oscillations, we have studied the magnetoconductance correlation function and the level-spacing distribution of the systems. The results allow us to interpret the rapid oscillations as an effect of the interference of electrons traveling along chaotic trajectories in the antidot lattices. The slow oscillations can be understood in terms of pinned electron orbits around groups of antidots.
