The current measured through the circuit indicates illumination of the device; the …
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 … WebPhotoconductive and photovoltaic modes There are two modes of operation for a junction photodiode: photoconductive and photovoltaic The device functions in photoconductive …
