CdS quantum dots (QDs) were formed on (001) GaAs and ZnSe (ZnSxSe1-x) by the self-assembled method. The nucleation process was monitored by RHEED and no evidence of a wetting layer formation was obtained. Photoluminescence (PL) peak energy shift was also obtained as a function of the volume of CdS deposit. The PL peak energy shift also implied that the wetting layer was not formed.
