| Abstract | Micro-arrayed patterns of p-type copper sulfide (CuxS) thin filmswith positive and negative featuresweredeposited onto the surfaces of n-type TiO2 semiconductor films via a selective nucleation and growthprocess from aqueous solution. The surface functional molecules of the UV photo-oxidised patternedSAMs were utilized to direct the nucleation and growth of CuxS crystallites. The resultant CuxS/TiO2composite films with negative and positive CuxS patterns on the TiO2 film surface were investigatedusing SEM, XRD, XPS and a 3D Surface Profiler. It is demonstrated that regular and compact patternedfilms of Cu2S crystallites had been deposited onto the n-type TiO2 surface,with sharp edges demarcatingthe boundaries between the patterned Cu2S region and the TiO2 film region. The UV–vis spectra forthree Cu2S/TiO2 films exhibit awide absorption between 300 nmand 450 nm. Themaximumwavelengthdifferences in the spectra of Cu2S/TiO2 films and TiO2 filmwere attributed to the added absorption of Cu2Sfilms at 302 nm and the unchanged adsorption of TiO2 films. The absorption intensities of the Cu2S/TiO2films could be varied in the UV–vis range using the Cu2S patterned features (positive, negative). |
