Abstract

We explore the switching characteristics of coupled quantum wires with a controllable interwire coupling. We perform extensive experimental and theoretical characterization of the coupling region between the wires, evaluating the local barrier that is formed in this region. With strong coupling between the wires, a nonmonotonic switching of their currents is obtained in a magnetic field, suggestive of quantum interference of electrons in their coupling region.
