摘要：

We consider magnetotransport properties of a strip of two-dimensional electron gas containing a single antidot potential at the center of the wire. Formation of a circulating edge channel around the anti-dot leads to an Aharonov-Bohm-type oscillation of the conductance as the magnetic field normal to the strip is varied. We find the appearance of resonant forward transmission as well as resonant reflection. The dependence of the resonances on the field strength and the sample parameters is discussed.
