Abstract

We discuss the formation of self-assembling II-VI quantum dots during MBE growth, with emphasis on CdSe dots grown on ZnSe. AFM measurements on specimens with uncapped dots show relatively narrow dot size distributions, with typical dot diameters of 52±6 nm. Uncapped CdSe dots are unstable with time, showing clear evidence of ripening. Photoluminescence from capped dots indicates strong exciton localization, as evidenced by very intense PL emission even at relatively high temperatures.
