the removal of electrons from a metallic conductor by a strong electric field.
the emission of electrons from a solid or liquid subjected to a high electric field
The emission of electrons from the surface of a conductor, caused by a strong electric field. Field emission is used to create electron beams in certain electron microscopes, as well as in flat-panel computer and television displays, in which the electron beams produce light by striking a phosphor-coated screen.
- Field emission display
hardware (FED) A type of flat panel display in which field emitting cathodes bombard a phosphor coating causing it to emit light. A field emission display is similar to a cathode ray tube but only a few millimeters thick. They use a large array of fine metal tips or carbon nanotubes (which are the most […]
