Vertical Growth of Cadmium Sulfide Crystals on a Silicon Substrate

The results of the technological and microscopy studies of the mechanisms of the vertical growth of cadmium sulfide crystals during vacuum synthesis from the vapor phase were reported. Whisker crystals with a diameter from 10 nm to a few micrometers and with a length of dozens of millimeters can be grown by the vacuum vapor phase synthesis in a quasi-closed volume. The results of studies are satisfactorily explained in terms of the classical vapor-liquid-crystal model. The SEM micrographs are presented.
