Abstract
InGaAs trench-type quantum wires (QWR) were fabricated using hydrogen-assisted molecular beam epitaxy. The trench-type QWR-field effect transistor (FET) showed negative differential conductance (NDC) characteristics with a low onset voltage and a high peak-to-valley current ratio (PVR). The magnetoresistance of the QWR-FET showed different behavior to that typically exhibited by disordered wires. An Aharonov-Bohm effect was used to study the interference process in which the one-dimensional subbands of the wire constituted well-resolved paths for electron interference.
