Schematic structure, optical microscopy, and SEM cross-section photograph. (a) The schematic structure of lift-off process to make micro/nano-holes by metal catalyst. (b) The optical microscopy of the Ag array (10 μm in hole diameter) after lift-off process. (c) The SEM cross-section photograph of microhole array. The nanowires were found inside microhole.
