Abstract
In this paper, a visible light blind ultraviolet sensor of a Schottky barrier photodiode using a ZnO single crystal is described. The sensor consists of a semitransparent Pt film for the Schottky electrode and Al thin film for the ohmic electrode on an n-type ZnO single crystal substrate grown by the hydrothermal method. The responsivity was 0.12 A/W at the wavelength of 365 nm and the photoresponse time was 12 μs.
