Thermionic Emission (Noun)
Meaning
The emission of electrons from very hot substances.
Classification
Nouns denoting natural processes.
Examples
- The thermionic emission of electrons from the hot cathode was the basis for the development of the first electronic amplifiers.
- Thermionic emission occurs when a metal is heated to a very high temperature, causing the electrons to escape from the surface.
- The thermionic emission of electrons from a heated filament is a fundamental process in the operation of vacuum tubes.
- In the early days of electronics, thermionic emission was used in devices such as vacuum tubes and rectifiers to control the flow of electric current.
- The study of thermionic emission led to a deeper understanding of the behavior of electrons in hot solids and its applications in various fields of physics and engineering.
