Carbon-assisted growth technology for ZnO nanowires

Using thermal evaporation of ZnO at high temperature in vacuum, we fabricated ZnO nanowires (NWs) directly on carbon-based materials (amorphous carbon and photoresist). SEM observations showed that ZnO NWs preferentially nucleate on carbon and grew perpendicularly to the surface of the carbon-based materials. Based on this new developed carbon-assisted growth technology, we realized large-area and patterned growth of high-quality ZnO NWs with low cost.
