Reduced temperature sensitivity of the polarization properties of hydrogenated InGaAsN V-groove quantum wires

We investigated the effects of hydrogen irradiation on the degree of linear polarization, rho, of the light emitted by site-controlled, dilute-nitride InGaAsN V-groove quantum wires (QWRs). While in the as-grown sample the polarization of the QWR emission is highly sensitive to the increasing temperature (T), after sample hydrogenation the value of rho remains nearly unchanged (and similar to 25%) for T
