field emission
the emission of electrons from a metal or semiconductor, under the influence of a strong electric field, by quantum tunneling
(Elektrik, Elektronik) Field electron emission (FE) (also known as field emission and - in some contexts - electron field emission) is a phenomenon involving the electric field induced emission of electrons from the surface of a condensed material (either solid or liquid), into vacuum or into another material. This second material may be a gas, a liquid, or a non-metallic solid with low electrical conductivity. FE occurs at surface locations where the local surface electric field is particularly high. To generate significant amounts of emission, fields of 1 volt per nanometre (1 V/nm, or 1 000 000 000 volts per metre) or more are required. The exact field needed depends both on the nature of the materials involved and on the amount of electron current being generated. No external stimulation (in particular, no heating) is needed
the emission of electrons that are stripped from parent atoms by a high electric field
The emission of electrons from the surface of a conductor, caused by a strong electric field
