A Schottky barrier photodetector with ZnO nanorods is fabricated on a glass substrate and the I-V characteristics are investigated. The ZnO nanorods are synthesized by an aqueous method, which allowed the fabricated Schottky barrier photodetector to be more sensitive in the UV region. Under 370-nm illumination, the photocurrent of the ZnO nanorod Schottky barrier photodetector is 6.56 μA and the UV-to-visible ratio is 780.8 at-1 V. In addition, the noise equivalent power and normalized detectivity (D) of the photodetector are 6.74,× 10-13W and 3.29,× 1011 cmHz0.5W-1 at-1m V, respectively.
