Abstract

Electronic transmission in a quasi-one-dimensional wire in the presence of a thin potential barrier is investigated in high magnetic fields. As the height of the barrier or magnetic field is varied, a regular structure is found to occur in the transmission through the barrier near propagation thresholds of edge states over the barrier. A coupling between the reflected edge states at each side of the barrier by means of tunneling makes an effective loop in the barrier region and leads to an Aharonov-Bohm-type oscillation.
