  • Abstract
    The introduction of a thin tensile-strained GaAs and In0.32 Ga0.68As right below the QD layer modulates the structural and optical properties of self-assembled InAs QDs embedded in an InAlGaAs matrix. The AFM images indicated that the average size of InAs QDs on GaAs/InAlGaAs is decreased compared to that without the thin GaAs layer, but ones on In0.32Ga0.68As/InAlGaAs are increased with more isotropic shape.
