Thermionic emission is the liberation of electrons from an electrode by virtue of its temperature. This occurs because the thermal energy given to the charge carrier overcomes the work function of the material.
What is the meaning of thermal emission?
Noun. 1. thermal emission - the emission of electrons from very hot substances. thermionic emission. emission - the release of electrons from parent atoms.
What is Richardson law statement?
A formula known as Richardson's law (first proposed by the English physicist Owen W. Richardson) is roughly valid for all metals. It is usually expressed in terms of the emission current density (J) as in amperes per square metre. The Boltzmann constant k has the value. In electron tube: Thermionic emission.
