Abstract

The ZnO nanowires, grown from two Au electrodes, were networked to allow the mechanism of photoconduction. It was found that the photocurrents through the nanowires excited by both the below-gap and above-gap light are surface-related. The rise and decay times of the photoresponses show that the trapping time of electrons ranges from 10 ms to several hours. The results show that the I-V characteristics of the photocurrent under the illumination of the below-gap light are Schottky, while those under the illumination of the above-gap light are ohmic.
