Low-Temperature Rapid Fabrication of ZnO Nanowire UV Sensor Array by Laser-Induced Local Hydrothermal Growth
Figure 6
(a) curves of the ZnO NW based UV sensors with single, double, and triple junctions. The current increases almost linearly with the number of junctions. (b) Time evolution of the current when the UV illumination is switched on and off for every 60 seconds at a fixed bias voltage.
