تعريف field emission في الإنجليزية الإنجليزية القاموس.

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

field emission display

a flat panel display technology that uses large-area field electron sources to provide electrons that strike coloured phosphors to produce a colour image. In a general sense, an FED consists of a matrix of cathode ray tubes, each tube producing a single sub-pixel, grouped in threes to form red-green-blue (RGB) pixels

field emission microscope

the instrument used in field emission microscopy

field emission microscopes

plural form of field emission microscope

field emission microscopy

a technique that uses field emission of electrons or positive ions from the needle-shaped tip of an emitter to produce a magnified image of the emitter surface (showing each atom) on a fluorescent screen
