TL;DR: In this paper, defect bound excitons were observed to be effectively passivated by hydrogenation and the preferential enhancement of excitonic features after hydrogenation. But they did not investigate the effect of hydrogenation on defect centers.
Abstract: Photoluminescence studies on ‘‘as‐grown’’ as well as hydrogenated undoped AlGaAs epitaxial layers grown by metalorganic vapor phase epitaxy has been carried out to study the effective passivation of defect centers. We report the observation of defect bound excitons which are effectively passivated by hydrogenation and the preferential enhancement of excitonic features after hydrogenation.
