Three-dimensional (3D) ZnO hybrid structure was fabricated by growing a ZnO buffer layer, a ZnO nanowire array, and a ZnO film continuously through the control of supersaturation conditions. Lower and upper ends of vertically aligned nanowires in this hybrid structure formed seamless interfacial contacts with the buffer layer and the film for current conduction. Photocurrent was generated only when the ultraviolet (UV) light (λ=350 nm) was irradiated. This structure also exhibited different atmosphere-dependent responses to the UV light. The optoelectronic properties of the 3D structure are attributed to the photogenerated carriers and the surface reaction of negatively charged oxygen species in ZnO nanowires.
