Graphite/ZnO nanorods junction for ultraviolet photodetectors

摘要

We report the fabrication of a graphite/ZnO nanorods (NRs) junction, which can act as a high-sensitivity ultraviolet (UV) photodetector, prepared by deposition of colloidal graphite on top of ZnO nanorod arrays obtained by low temperature hydrothermal growth. The photodetector is shown to be highly sensitive in a wide range of UV illumination intensities.
