WebApr 14, 2024 · where q is the amount of electronic charge and η is the quantum efficiency. In general, quantum efficiency (η) refers to the external quantum efficiency (EQE).A is the photosensitive area of the detector, ϕ is the incident flux of DUV light, and g is the photoconductive gain.. Dark current (I dark, I d) generated by DUV detectors without … Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation. When light is absorbed by a material such as a semiconductor, the number of free electrons and holes increases, resulting in increased electrical conductivity. To cause excitation, the light that …
