Abstract

We study the magneto-resistance of a V-grooved GaAs quantum-wire field-effect transistor (QWR-FET) realized by selective growth of metalorganic vapor phase epitaxy. At low temperatures, the magneto-resistance of the wire shows reproducible fluctuations resulting from the quantum interference of electrons in the wire. The gate-voltage and temperature dependence of the conductance fluctuations are studied, and the latter reveal evidence for the robust phase coherence of electrons in the V-grooved QWR.
