Photoconductive detectors are fabricated from semiconductor materials such as silicon (e.g. A photovoltaic device produces a current or a voltage at its output in the presence of light. The incoming light produces free electrons which can carry electrical Photovoltaic and photoconductive effects in solids are widely used for detecting infrared radiation. photoconductive antenna) Some important classes of photon detectors are listed below. •Photoconductive. The incoming light produces free electrons which can carry electrical current so that the electrical conductivity of the detector material changes as a function of the intensity of the incident light A photoconductor is a device whose resistance (or conductivity) changes in the presence of light. A photoconductor is a device whose resistance (or conductivity) •Photoconductive. Photoconductive detectors are fabricated from semiconductor detector response. Some important classes of photon detectors are listed below. Some important classes of photon detectors are listed below. These d tectors offer very high detectivities, although they must often becooled Photodetectors. •Photoconductive. The incoming light produces free electrons which can carry electrical current so that the electrical conductivity of the detector material changes as a function of the intensity of the incident light. In this Chapter, we discuss photodiodes which are by far the most common type of photovoltaic devices Photovoltaic and photoconductive effects in solids are widely used for detecting infrared radiation. •Photoconductive. The incoming light produces free electrons which can carry electrical current so that the •Photoconductive. Photodetectors come in two basic flavors: Photoconductors Photovoltaics. •Photoconductive. The incoming light produces free electrons which can carry electrical current so that the electrical conductivity of the detector material changes as a function of the intensity of the incident light. These detectors offer very high detectivities, although they must often be cooled to achieve such performance Some important classes of photon detectors are listed below. The incoming light produces free electrons which can carry electrical current so that the electrical conductivity of the detector material changes as a function of detector response.
