英文摘要	Micro-arrayed patterns of p-type copper sulfide (cuxs) thin films with positive and negative features were deposited onto the surfaces of n-type tio2 semiconductor films via a selective nucleation and growth process from aqueous solution. the surface functional molecules of the uv photo-oxidised patterned sams were utilized to direct the nucleation and growth of cuxs crystallites. the resultant cuxs/tio2 composite films with negative and positive cuxs patterns on the tio2 film surface were investigated using sem, xrd, xps and a 3d surface profiler. it is demonstrated that regular and compact patterned films of cu2s crystallites had been deposited onto the n-type tio2 surface, with sharp edges demarcating the boundaries between the patterned cu2s region and the tio2 film region. the uv-vis spectra for three cu2s/tio2 films exhibit a wide absorption between 300 nm and 450 nm. the maximum wavelength differences in the spectra of cu2s/tio2 films and tio2 film were attributed to the added absorption of cu2s films at 302 nm and the unchanged adsorption of tio2 films. the absorption intensities of the cu2s/tio2 films could be varied in the uv-vis range using the cu2s patterned features (positive, negative).
