WebAt zero bias, the advanced ε-Ga2O3/ZnO photodetector performs decent self-powered photoelectrical properties with photo-to-dark current ratio of 1.28×105, on/off switching ratio of 3.22×104, rise/decay times of 523.1/31.7 ms, responsivity of 4.12 mA/W and detectivity of 2.24×1012 Jones. The prominent photodetection performance lays a solid ... The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the … See more The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy … See more 19th century In 1839, Alexandre Edmond Becquerel discovered the photovoltaic effect while studying the effect of light on electrolytic cells. … See more When photon energies are as high as the electron rest energy of 511 keV, yet another process, the Compton scattering, may take place. Above twice this energy, at 1.022 MeV pair production is also more likely. Compton scattering and pair production are … See more Photomultipliers These are extremely light-sensitive vacuum tubes with a coated photocathode inside the envelope.
