ABSTRACT:
A field emission element features an emitter which has rectangular projections at its distal end capable of readily controlling the interval between electrodes in increments as small as sub-microns, in order to reduce the voltage at which the device starts field emission at the required level and to improve emission uniformity. An emitter (2,20), a collector (3,21) and a gate (5,22) are arranged on a substrate (1), which is formed with a recess (4) in proximity to the electrodes (2,3,20,21) other than the gate (5). The gate (5) is provided in the recess (4).
