Multiwalled carbon nanotubes/ZnO nanowires composite structure with enhanced ultraviolet emission and faster ultraviolet response

We report on the fabrication of multiwalled carbon nanotubes (MWCNTs)/ZnO nanowires (NWs) composite structures. The composite structure shows enhanced ultraviolet emission and faster ultraviolet photoresponse time constants for multiple MWNTs coatings (n = 5 and 2) compared to the bare ZnO NWs.
