Photoconductors
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 Some materials exhibit deterioration in photoconductivity upon exposure to illumination. One prominent example is hydrogenated amorphous silicon (a-Si:H) in which a metastable reduction in photoconductivity is observable (see Staebler–Wronski effect See more The characterization technique called photoconductivity spectroscopy (also known as photocurrent spectroscopy) is widely used in studying optoelectronic properties of semiconductors. See more Sensitization is an important engineering procedure to amplify the response of photoconductive materials. The photoconductive gain is proportional to the lifetime of photo-excited carriers (either electrons or holes). Sensitization involves intentional … 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 magnetization melting was also demonstrated thus could be used in magneto optical … See more • Photodiode • Photoresistor (LDR) • Photocurrent See more WebFeb 16, 2024 · For the n-type photoconductors, the n + regions were created by diffusion doping, while for the p-type photoconductors, boron implantation was employed to create the p + regions. Afterward, the thermal oxide was entirely removed from the front and back side of both n- and p-type wafers by BHF etching. This was followed by aluminum (Al) film ...

Webanode and cathode. Electronic symbol. A photodiode is a light-sensitive semiconductor diode. [1] It produces current when it absorbs photons. The package of a photodiode allows light (or infrared or ultraviolet radiation, or X-rays) to reach the sensitive part of the device. The package may include lenses or optical filters. WebJan 1, 2024 · Thus, only amorphous or polycrystalline (poly)photoconductors are currently practical for use in large-area x-ray imaging detectors. Amorphous selenium (a-Se) is one of the most highly developed photoconductors for large-area detectors due to its commercial use in photocopiers and laser printers as an electrophotographic photoreceptor . In fact ...
