text: Electron emission arises when part of the electrons in a body gain sufficient energy, under the influence of external factors, to overcome the potential barrier at the boundary of the body or when the surface potential barrier, under the action of an electric field, becomes transparent to part of the electrons that have the highest energies within the body.
