Abstract
We study electron transport in an antidot superlattice with a finite number of periods. At low carrier densities and high magnetic fields the electrons travel phase coherently over the entire system in magnetic edge channels and interfere with each other under the influence of the geometry of the antidot potential landscape. The magnetoresistance displays pronounced Aharonov-Bohm-type oscillations arising from electrons that travel along the bound states that form around the antidots. The characteristic period of the oscillations is given by the area defined by the circumference of the antidots.
