An electron emission layer made of material having small work function such as a diamond thin film is formed on the bottom portion of the concave portion. A protruding portion of the substrate serves as a beam formation electrode. Divergence of electrons can be suppressed with the beam formation electrode. A gate electrode for drawing out the electrons is formed above the beam formation electrode.

    Abstract: A field emission display having a diamond thin film having a low work function due to its affinity for electrons used for forming a micro-tip. Electron emitting micro-tips are manufactured using diamond or diamond-like carbon which have a low work function due to their affinity for electrons, and thereby facilitate electron emission at a very low gate voltage. Manufacturing a flat micro-tip allows uniform tips to be formed so that a large device can be easily fabricated.

    Abstract: Improved field-emission devices are based on composing the back contact to the emitter material such that electron-injection efficiency into the emitter material is enhanced. Alteration of the emitter material structure near the contact or geometric field enhancement due to contact morphology gives rise to the improved injection efficiency. The devices are able to emit electrons at high current density and lower applied potential differences and temperatures than previously achieved. Wide-bandgap emitter materials without shallow donors benefit from this approach. The emission characteristics of diamond substitutionally doped with nitrogen, having a favorable emitter/vacuum band structure but being limited by the efficiency of electron injection into it, show especial improvement in the context of the invention. The injection-enhancing contacts can be created by combining the emitter material with an appropriate metal compound and annealing or by conventional dry anisotropic etching or ion bombardment techniques.

    Abstract: In accordance with the invention, a field emission device is made by disposing emitter material on an insulating substrate, applying a sacrificial film to the emitter material and forming over the sacrificial layer a conductive gate layer having a random distribution of apertures therein. In the preferred process, the gate is formed by applying masking particles to the sacrificial film, applying a conductive film over the masking particles and the sacrificial film and then removing the masking particles to reveal a random distribution of apertures. The sacrificial film is then removed. The apertures then extend to the emitter material. In a preferred embodiment, the sacrificial film contains dielectric spacer particles which remain after the film is removed to separate the emitter from the gate. The result is a novel and economical field emission device having numerous randomly distributed emission apertures which can be used to make low cost flat panel displays.

    Abstract: A matrix addressable flat panel display includes a flat cathode operable for emitting electrons to an anode when an electric field is produced across the surface of the flat cathode by two electrodes placed on each side of the flat cathode. The flat cathode may consist of a cermet or amorphic diamond or some other combination of a conducting material and an insulating material such as a low effective work function material. The electric field produced causes electrons to hop on the surface of the cathode at the conducting-insulating interfaces. An electric field produced between the anode and the cathode causes these electrons to bombard a phosphor layer on the anode.
