Photoconductive detector
Did you know?
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 detectors have a bulk resistance which is temperature dependent. For lead salt photoconductive films this temperature dependency is typically on the order of 3 %/°C. The problem is that if the bulk resistance is changing due to temperature variations it can be indistinguishable from the photoconductive signal. Modulation of the ...
WebApr 13, 2024 · The demand for ultrahigh-speed, lightweight, low-cost, and defect-tolerant electronic devices drives the industry to switch to terahertz (THz) technologies. The use of two-dimensional (2D) materials has massively increased in THz applications due to their appealing electronic and optoelectronic properties, including tunable bandgap, high … WebThe OSI Optoelectronics / United Detector Technology Photoconductive Detector Series Planar Diffused Silicon Photodiodes are suitable for high speed and high sensitivity applications.

Infrared radiation generates charge carriers in the semiconductor active region decreasing its resistance. … WebInfrared Photoconductive Detectors Infrared light at wavelengths sometimes beyond 5 μm can be detected with lead salt detectors, e.g. containing lead selenide (PbSe) or lead sulfide (PbS). Such devices are not fabricated with epitaxial growth, as e.g. InGaAs photodiodes, but rather by deposition of thin polycrystalline films.
