- and Magneto-Transport Studies of Single Inas Quantum Wires

In this work we investigate the low-dimensional electron gas confined in single quantum wires by employing magneto-transport measurements and far-infrared photoconductivity spectroscopy. The quantum wires were fabricated from InAs/InGaAs/InAlAs heterostructures ranging from 4 μm down to 400 nm in width. We demonstrate the feasibility of photoconductivity spectroscopy on single InAs quantum wires for the first time.
