Abstract

Transport properties of a quasi-ballistic wire with a point-contact (PC) in one-side boundary were studied. In the two-terminal resistance of the wire, when the width were sufficiently narrow, we have observed two competing sets of plateaus. They were able to be distinguished with each other by their different behaviours against variations of a sample size as well as a boundary condition. One of the plateau sets among them was found to originate from the PC itself in the wire boundary. This result indicates a possibility of a new class of narrow wires having a specific transport property due to the tailored quantum boundaries connecting with reservoirs or another wires.
