Low-Temperature Rapid Fabrication of ZnO Nanowire UV Sensor Array by Laser-Induced Local Hydrothermal Growth
Figure 3
(a) Optical images of ZnO NW array grown using laser-induced hydrothermal growth for 5 min, 10 min, 15 min, 20 min, and 25 min and 30 min and (b) the corresponding SEM images. (c) Plot of the ZnO NW length at different growth time. It is noticeable that the growth rate of laser-induced hydrothermal process is much faster than the conventional bulk growth.
