Photoemission may refer to:
- Electron emission from matter after the absorption of energetic photons. The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J In Physics, the photon is the Elementary particle responsible for electromagnetic phenomena (See photoelectric effect). Introduction When a Metallic surface is exposed to Electromagnetic radiation above a certain threshold Frequency, the light is absorbed and Electrons
- Photon emission from semiconductors and metals when electrons flowing in the material lose energy by decelerating or recombining. Bremsstrahlung ( pronounced, from German de ''bremsen'' "to brake" and de ''Strahlung'' "radiation" i In the Solid state physics of Semiconductors carrier generation and recombination are processes by which mobile Electrons and Electron holes
