✦ Synopsis

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

The distribution of electron current in GaAs=AlGaAs v-groove quantum wire structures with groove widths varying from 1 to 25 m has been studied using far-and near-ΓΏeld spectroscopy techniques. We ΓΏnd clear evidence of the formation of 'corner' quantum wires in wide grooves which coalesce to form sin
