Effects Of Hydrogen Irradiation On The Optical And Electronic Properties Of Site-controlled InGaAsN V-groove Quantum Wires

The properties of InGaAsN V-groove quantum wires (QWRs) - both untreated and irradiated with atomic hydrogen-are probed via micro-magneto-photoluminescence (PL) and polarization-dependent PL. As generally observed in dilute-nitride materials, H irradiation is found to fully passivate nitrogen, thus allowing us to accurately assess - and to precisely control-the effects of N incorporation in the QWRs.
