[feeld-i-fekt] /ˈfild ɪˌfɛkt/
a transistor in which the output current is varied by varying the value of an electric field within a region of the device.
a unipolar transistor consisting of three or more electrode regions, the source, one or more gates, and the drain. A current flowing in a channel between the highly doped source and drain is controlled by the electric field arising from a voltage applied between source and gate FET See also JFET, IGFET
noun, Physics. 1. the removal of electrons from a metallic conductor by a strong electric field. noun 1. the emission of electrons from a solid or liquid subjected to a high electric field field emission The emission of electrons from the surface of a conductor, caused by a strong electric field.

- 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 […]
