thermionic emission
1. The emission of electrons or ions by substances that are highly heated, the charged particles being called thermions.
2. The discharge of electrons or ions from a solid or liquid as a result of its thermal energy.
3. The release of electrons when a material is heated; for example, electron emission when the tungsten cathode filament of a radiographic tube is heated to incandescence (emission of light by an object as a result of its being heated to a high temperature) by means of its low-voltage heating circuit.
