Abstract :
In order to develop a high-gain ultraviolet (UV) detector with low operation voltage and low fabrication cost, a photodetector that consists of a diamond cold cathode and selenium-based photoconductive film was proposed. It was confirmed that the illumination of UV light increases field emission current with a fixed applied voltage, proving that the prototype photodetector can detect UV light.
