The characteristics of quantum well intermixing in GaInNAs/GaAs structures of differing N content were discussed. 1.3 μM GaInNAs/GaAs multiquantum wells were disordered using rapid thermal annealing and SiO 2 caps deposited on the surface of samples. The dependence of quantum well intermixing-induced photoluminescence blueshift on N concentration was studied. It was found that the blueshift decrease as the nitrogen concentration increases.
