Abstract: The film and bulk material of zinc sulphide were prepared by chemical vapor deposition. The nucleation and the growth of zinc sulphide crystals deposited on the graphite and quartz substrates withdifferent roughness were observed. The grAlNs of zinc sulphide deposited on the substrate surface are veryfine, with equiaoxial shape, and then grow up into columnar shape. The roughness of the substrate surfaceinfluences the nucleation density of zinc sulphide but has no effect on the growth rate of zinc sulphide increases with increasing the flow of H2S and vapoured Zn. The growth rate exhibits maxium value at a given deposition temperature.

Key words: chemical vapor deposition, zinc sulphide, crystal growth
