Abstract: An apparatus for emitting electrons is provided. The apparatus includes a subsurface emitter having a sharp tip, a substrate including a base, and electrical continuity between the tip, the base, and an external circuit. This emitter structure may be used to form individual emitters or arrays of emitters. Also provided is a method of making electron emitters which is comprised of implanting energetic ions into a diamond lattice to form cones or other continuous regions of damaged diamond. These regions are more electrically conducting than the surrounding diamond lattice, and have locally sharp tips at or near the point of entry of the ion into the diamond. The tips may then also be additionally coated with a layer of a wide band-gap semiconductor. An electrically conducting material may also be placed in proximity to the tips to generate an electric field sufficient to extract electrons from the conducting tips into either the region above the surface, or into the wide band-gap semiconductor layer in contact with the tips. Electrical contact is made to the electrically conducting damage tracks and the electrical circuit may be completed with an electrically conducting material on the surface of the wide band-gap semiconductor or diamond, or in the ambient above the surface of the emitter. The surface of the wideband gap semiconductor or diamond may be chemically modified to enhance the emission of electrons from the surface.

Abstract: A field emission display device (1) includes a cathode plate (20), a resistive buffer (30) in contact with the cathode plate, a plurality of electron emitters (40) formed on the buffer, and an anode plate (50) spaced from the electron emitters. Each electron emitter includes a rod-shaped first part (401) and a conical second part (402). The buffer and first parts are made from silicon oxide. The combined buffer and first parts has a gradient distribution of electrical resistivity such that highest electrical resistivity is nearest the cathode plate and lowest electrical resistivity is nearest the anode plate. The second parts are made from niobium. When emitting voltage is applied between the cathode and anode plates, electrons emitted from the electron emitters traverse an interspace region and are received by the anode plate. Because of the gradient distribution of electrical resistivity, only a very low emitting voltage is needed.

Abstract: An electron field emission device is provided by placing a substrate in a reactor, heating the substrate and supplying a mixture of hydrogen and a carbon-containing gas at a concentration of about 8 to 13 per cent to the reactor while supplying energy to the mixture of gases near the substrate for a time to grow a first layer of carbon-based material to a thickness greater than about 0.5 micrometers, subsequently reducing the concentration of the carbon-containing gas and continuing to grow a second layer of carbon-based material, the second layer being much thicker than the first layer. The substrate is subsequently removed from the first layer and an electrode is applied to the second layer. The surface of the substrate may be patterned before growth of the first layer to produce a patterned surface on the field emission device. The device is free-standing and can be used as a cold cathode in a variety of electronic devices such as cathode ray tubes, amplifiers and traveling wave tubes.

Abstract: This disclosure is directed toward field emission surfaces, and is more particularly directed toward improvements in cold, low field, high current, low noise field emission devices and surfaces. Such devices are used in field emission display devices such as video displays and information displays. The device utilizes a cermet with graded concentration of insulative and conductive particles deposited on the truncated point of a conical emitter. The emission surface of the cermet is insensitive to gases that oxidize or poison the emission surface. Such gases and other contaminants emanate from a phosphor when the emission device is used in phosphor display devices. The field emission device is operated at lower potentials thereby reducing power requirements and minimizing heat dissipation requirements. Further, the field emission device which operates at lower field in order to reduce mechanically and temporally unstable emission sites which result in current bursts and current deficits at these sites. Still further, the field emission device incorporates internal resistors which provide series resistance to limit noise at affected emission areas thereby eliminating the need to limit noise by incorporating high-valued resistors, typically in series with the cathode terminal of the emission device, which reduce the potential to the entire emission surface and increasing potentials required to produce current sufficient to excite display phosphor.
