Cross-sectional transmission electron microscope observation was performed on GaAs-AlAs multi-quantum-well (MQW) structures which were compositionally disordered by ion implantation of the constituent element Ga+ and subsequent heat-treatment, and compared with MQW structures implanted by other species of ions As+, Si+ and Ar+. It was found that most of the defects introduced by ion implantation of Ga+ are annealed out by heat treatment at 750°C for 60 minutes, and that this is also the case for defects introduced by ion implantation by another constituent element As+, while many of the defects introduced by Si+ and Ar+ ion implantation remain without being annealed out.
