Tribenzyltin(IV) chloride Thiosemicarbazones: Novel Single Source Precursors for Growth of SnS Thin Films

Tin sulfide (SnS) thin films are deposited using simple tin thiosemicarbazone complexes of the type Bz(3)SnCl(L) (L = thiosemicarbazones of salicylaldehye and 4-chlorobenzaldehyde). Thin films are deposited using aerosol-assisted (AA) CVD in the range 375-475 degrees C. X-ray diffraction (XRD) shows the formation of SnS regardless of growth temperature and precursor type. Scanning electron microscope (SEM) images show that the films have wafer-like morphology, and the growth temperatures do not have a profound effect on morphology.
