Photoconductivity is an optical and electrical phenomenon, which material's electrical conductivity increase by absorption of electromagnetic radiation (e.g. visible light, ultraviolet light, infrared light). Photoconductive polymers can serve as good insulators when the electricity, free electrons and holes are absent. In general, the polymers usually satisfy these two features. WebJan 1, 1999 · GaN photoconductive detectors have been fabricated on sapphire substrates by metal organic vapor phase epitaxy and gas-source molecular beam epitaxy on Si (111) substrates. The photodetectors ...

photoconductivity - Wiktionary

WebPhotoconductivity (also photoconductive effect), the increase in the electrical conductivity of a semiconductor when the semiconductor is exposed to electromagnetic radiation. Photoconductivity was first observed in selenium by W. Smith (Great Britain) in 1873. WebX-ray-induced photoconductivity has been measured in low-density polyethylene, Tefzel ‡ (Dupont fluorocarbon), Durasan (Dupont fluorocarbon), polychlorotrifluoroethylene (Kel-F), polystyrene, polypropylene, polyvinylidene chloride, polyvinylidene fluoride, polyvinyl chloride and mica. Dose rates varied in the range 109 - 5 × 1010 rad/s. The observed … how do you get on the korn ferry tour

Photoconductivity physics Britannica

WebIn an extrinsic material for impurity band detectors, one exploits additional energy levels introduced by impurities.These are introduced by doping with additional chemical species and provide additional excitation pathways. High doping concentrations are preferable to obtain strong absorption, so that rather thin layers can be used; only, for too high doping … WebAs nouns the difference between conductivity and photoconductivity is that conductivity is the ability of a material to conduct electricity, heat, fluid or sound while photoconductivity is (physics) an increase in the electrical conductivity of a material as a result of incident electromagnetic radiation.
