Low-Temperature Rapid Fabrication of ZnO Nanowire UV Sensor Array by Laser-Induced Local Hydrothermal Growth
Figure 2
ZnO NW array synthesized using laser-induced hydrothermal growth at 120 mW power for 30 min using 5X objective lens. (a) SEM image of ZnO NW array synthesized by laser-induced hydrothermal growth. ZnO NW array consists of individual NWs facing radial direction with ~8 μm and length, is synthesized only at the laser spot. (b) SEM image of ZnO NW array with higher magnification. Distinct facets are observable, while the thickness of each NW is 200~400 nm. (c) TEM image of a single ZnO NW, showing the lattice arrangement along -axis.
