Fabrication of patterned CdS/TiO2 heterojunction by wettability template-assisted electrodeposition

Fabrication of patterned CdS/TiO2 heterojunction by wettability template-assisted electrodeposition

A wettability template-assisted process was applied to selectively deposit cadmium sulfide (CdS) nanospheres on TiO2 nanotube layers to form uniformly coupled CdS/TiO2 semiconductor heterojunction micropatterns. The effect of deposition time on the size and morphology of the as-prepared CdS/TiO2 arr...
