Electron emission

Summary

In physics, electron emission is the ejection of an electron from the surface of matter,[1] or, in beta decay (β− decay), where a beta particle (a fast energetic electron or positron) is emitted from an atomic nucleus transforming the original nuclide to an isobar.

Radioactive decayEdit

Surface emissionEdit

DevicesEdit

  • An electron gun or electron emitter, is an electrical component in some vacuum tubes that uses surface emission
