The properties of single InGaAsN V-groove quantum wires (QWRs) –both untreated and irradiated with atomic hydrogen– are probed by micro-magneto-photoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orientations of the applied magnetic field confirms the one-dimensional nature of the QWR carrier wavefunction. In addition, the strain reduction associated with N incorporation is found to promote a larger indium intake in the QWR, enabling the realization of sitecontrolled QWRs emitting at long (≥1.3μm), technologically relevant wavelengths.

Abstract
The properties of single InGaAsN V-groove quantum wires (QWRs) –both untreated and irradiated with atomic hydrogen– are probed by micro-magneto-photoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orientations of the applied magnetic field confirms the one-dimensional nature of the QWR carrier wavefunction. In addition, the strain reduction associated with N incorporation is found to promote a larger indium intake in the QWR, enabling the realization of sitecontrolled QWRs emitting at long (≥1.3μm), technologically relevant wavelengths.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
