More example sentences
  • 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.
  • So far, searches for this separation have concentrated on detecting its effect on many-body correlation functions with photoemission, optical, magnetic or tunnelling spectroscopies.



More example sentences
  • 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.
  • 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.


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