Evolution of Gaas capping layer on in0.5Ga0.5As/Gaas quantum dots structure
Self-assembled InxGai_xAs/GaAs quantum dots were grown with and without GaAs capping layer. Effect of different growth condition on the capping layer was studied using atomic force microscope (AFM). The optical properties o f capped quantum dots structure was investigated by photoluminescence (PL) m...
