Article Description

Quantum interference effects are observed in a GaAs/AlxGa1-xAs interferometer which consists of double quantum wires and triple Schottky gates. Both wires are straight, stacked in the growth direction, and coupled via a thin barrier. The electron wave function is controlled by tuning the gate voltages in such a way that an interferometer is constructed in the straight wires. A quasiballistic electron transport was confirmed, and oscillations of resistance with variation of the voltage of the central gate are clearly observed at 1.8 K. © 1993 The American Physical Society.
