Definition of photoemission in English:

photoemission

noun ˈfəʊtəʊɪˌmɪʃ(ə)nˌfoʊdoʊəˈmɪʃ(ə)n
mass noun
  • The emission of electrons from a surface caused by the action of light striking it.

    光电 (子)发射

    Example sentencesExamples
    • Experiments have demonstrated that removing an electron from a metal results in a very narrow peak in the photoemission spectrum.
    • In the 1950s, researchers began measuring binding energies of core electrons by x-ray photoemission.
    • They then imaged the sample with x-ray photoemission electron microscopy, a recently developed technique that gives a microscopic map of the magnetic structure.
    • The papers in this special issue demonstrate some of the new directions in photoemission.
    • So far, searches for this separation have concentrated on detecting its effect on many-body correlation functions with photoemission, optical, magnetic or tunnelling spectroscopies.

Derivatives

  • photoemissive

  • adjective
    • It has been used to give, at least approximately, the dynamics of photoemissive sources such as an atom absorbing and emitting light or matter in an optical cavity, which exchanges light with the surrounding free space.
      Example sentencesExamples
      • In the experiment, we found that when activated by cesium, the indium tin oxide (ITO) thin film would have a photoemissive effect under the radiation of visible light.
  • photoemitter

  • noun
    • This photoemitter controls the placement as well as the width of bits of information recorded on magnetic tape.
      Example sentencesExamples
      • The optical coupler is mounted in a lower part of the casing, and has a photoemitter and a photoreceiver that faces the photoemitter.
