Growth of ZnS films by chemical vapour deposition of Zn[(S2CN(CH3)2]2 precursor

Crystalline ZnS films have been grown on a variety of substrates using chemical vapor deposition from zinc dimethyl dithiocarbamate Zn[S2CN(CH3)2]2 as a single source precursor. Transmission electron microscopy and X-ray diffraction indicated that the films were composed of a uniform array of columns with cubic [1 1 1] orientation. Depth profile X-ray photoemission spectroscopy indicated that the impurity concentration remained less than 1 atomic percent (at%) in the bulk of the films. Chemical vapor deposition of zinc dimethyl dithiocarbamate offers advantages over previous precursors to improve significantly the physico-chemical properties of ZnS films.
