MOCVD Preparation of Polycrystalline ZnS Films with Pronounced Columnar Grains

ZnS films having good crystallinity are grown on glass by MOCVD using dimethylzinc and diethylsulphide. These films consist of very pronounced columnar grains that extend from the bottom to the top of the film. The crystal structure of these films is hexagonal. Thin film electroluminescent devices are fabricated using these films and their characteristics are measured.
