摘要	ZnCdSe quantum dots (QDs) were fabricated successfully under Stranski-Krastanow mode by metalorganic chemical vapor deposition. Prior to growth, the critical thickness was first calculated in terms of strain relaxation and the growth was then performed with the help of the calculation. The evolution of the QDs was also studied by atomic force microscopy and spectroscopy. Two kinds of variations in the QDs appeared over time, the Ostwald ripening process and dot-formation process. Moreover, the shape of the dots changed from pyramidlike to domelike, with the transition explained by the theory of crystal growth. By analyzing photoluminescence spectra, two emission mechanisms were revealed and were thought to be zero-dimensional (OD) and 2D-like excitons. With increasing growth interruptions, the luminescence intensity ratio of the 0D to 2D-like excitons increased, which gave further evidence of the evolution of QDs. (C) 2002 American Vacuum Society.
