A silver thin film is introduced as a temporal template and dopant source for vertically aligned p-n homojunction of ZnO nanorods. The growth of Ag-doped ZnO nanorods was observed over time and the doping effect was determined through various characterization methods. Furthermore, a p-n homojunction diode of ZnO nanorods was fabricated.
