Abstract

In order to clarify the quantum interference effect in corrugation gated wires of GaAs/AlGaAs, we have studied the negative magnetoresistance (NMR) peak and discussed localization effect of the electron wave in the wire. As the width decreases, the NMR becomes to decrease linearly and the Lorentzian peak changes into a triangular shape. Because of the larger NMR peak by one order than that in the single dot, it suggests that a certain trapping motion in a small area near the wire boundary is related to the origin of the large NMR.
