Abstract
We present a systematic investigation of transient photoluminescence i n GaAs V-shaped Quantum Wires as a function of temperature, aimed at t he understanding of the radiative recombination mechanism of the groun d level (localized vs free exciton recombination). Exciton localizatio n energy, density of localization centres and exciton-intrinsic Lifeti me have been determined from the theoretical analysis of the transient photoluminescence spectra.
