We present our recent investigations on the self-organized growth and optical properties of quantum structures including CdSe quantum dots (QDs) embedded in ZnSe, ZnSe QDs in ZnS, and ZnO quantum pyramids. The self-organized mechanism is shown to play an important role in the formation of CdSe QDs on ZnSe(111). The ZnSe QDs are found to form on a 1 ML thick ZnSe wetting layer embedded in ZnS(100). The self-organized ZnO quantum pyramids form on ZnO(0001) buffer layers through preferred facet nucleation rather than strain-induced islanding.
