We report the photoluminescence study of low-energy, low-dose oxygen implantation induced compositional disordering of AlGaAs/GaAs quantum well structures. Significant disordering of both single and multiple AlGaAs/GaAs quantum wells has been achieved using low-energy (155 keV) oxygen ion implantation with doses as small as 5 x 10(13) cm-2 after a moderate annealing step. These doses are significantly lower than those reported previously (500 keV and 10(16) cm-2).
