The
emission of electrons
from the surface of a metallic conductor
into a vacuum
(or into an insulator)
under influence of a strong electric field. In field emission, electrons penetrate through the potential surface
barrier by virtue of the quantum-mechanical tunnel effect. Also known as cold
emission. See also electrontunneling.
