Figure 4From: Enhanced UV photosensitivity from rapid thermal annealed vertically aligned ZnO nanowires The photocurrent spectra of the ZnO NWS. (a) as-grown, (b) RTA treated at 700°C, and (c) RTA treated at 800°C, respectively at a bias voltage of 2.5 V. The inset of (c) shows the variation of photosensitivity at different intensity of UV light (wavelength 369 nm) for the ZnO NWs RTA treated at 800°C.Back to article page
