WebPhotoconductivity in semiconductors: Absorption of photons create excited photocarriers which are quickly swept by bias Electric field (E field causes drift) (if they drift ... and gain enough energy to ionize atoms in the valance band if they collide, thus releasing more e-h pairs. This process of carrier 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, … See more When a photoconductive material is connected as part of a circuit, it functions as a resistor whose resistance depends on the light intensity. In this context, the material is called a photoresistor (also called light … See more In 2016 it was demonstrated that in some photoconductive material a magnetic order can exist. One prominent example is CH3NH3(Mn:Pb)I3. In this material a light induced … See more • Photodiode • Photoresistor (LDR) • Photocurrent See more Sensitization is an important engineering procedure to amplify the response of photoconductive materials.
