Electron emission
In physics, electron emission is the ejection of an electron from the surface of matter, or, in beta decay, where a beta particle is emitted from an atomic nucleus transforming the original nuclide to an isobar.
Radioactive decay
- In Beta decay, radioactive decay results in a beta particle being emitted from the nucleus
Surface emission
- Thermionic emission, the liberation of electrons from an electrode by virtue of its temperature
- * Schottky emission, due to the:
- ** Schottky effect or field enhanced thermionic emission
- Field electron emission, emission of electrons induced by an electrostatic field
Devices
- An electron gun or electron emitter, is an electrical component in some vacuum tubes that uses surface emission
Others
- Exoelectron emission, a weak electron emission, appearing only from pretreated objects
- Photoelectric effect, the emission of electrons when electromagnetic radiation, such as light, hits a material
