Abstract: An enhanced Spindt-tip field emitter tip and a method for producing the enhanced Spindt-tip field emitter. A thin-film resistive heating element is positioned below the field emitter tip to allow for resistive heating of the tip in order to sharpen the tip and to remove adsorbed contaminants from the surface of the tip. Metal layers of the enhanced field emission device are separated by relatively thick dielectric bilayers, with the metal layers having increased thickness in the proximity of a cylindrical well in which the field emitter tip is deposited. Dielectric material is pulled back from the cylindrical aperture into which the field emitter tip is deposited in order to decrease buildup of conductive contaminants and the possibility of short circuits between metallic layers.

Abstract: A method for fabricating an electron emitter is provided. This emitter structure may be used to form individual emitters or arrays of emitters. The method 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 high resolution field emission display includes a faceplate and a baseplate. The faceplate includes a transparent viewing layer, a transparent conductive layer formed on the transparent viewing layer and intersecting stripes of light-absorbing, opaque insulating material formed on the transparent conductive layer. The insulating material defines openings less than one hundred microns wide between the intersecting stripes. The faceplate also includes a plurality of localized regions of cathodoluminescent material, each formed in one of the openings. The cathodoluminescent material includes a metal oxide providing reduced resistivity in the cathodoluminescent material. Significantly, the reduced resistivity of the cathodoluminescent material together with the focusing effect of the insulating material provide increased acuity in luminous images formed on the faceplate. The baseplate includes a substrate, an emitter formed on the substrate and a dielectric layer formed on the substrate and having an opening formed about the emitter. The baseplate also includes a conductive extraction grid formed on the dielectric layer and having an opening formed about the emitter.

Abstract: A method of fabricating row lines and pixel openings of a field emission array. The method employs only two masks. A first mask employed in the method includes apertures alignable between rows of pixels of the field emission array. Electrically conductive material and semiconductive material exposed through the apertures are removed to define the row lines of the field emission array. A passivation layer is then disposed over at least selected portions of the field emission array. Then a second mask, including apertures alignable over the pixel regions of the field emission array, is disposed over the passivation layer of the field emission array. Passivation material exposed through the apertures of the second mask is removed to define openings through the passivation layer and over the pixel regions of the field emission array. Conductive material exposed through the apertures of the second mask may then be removed to expose the underlying semiconductive grid and to further define the pixel openings.

Abstract: The present invention provides a DBD lamp used in fluid treatment systems, where the irradiated fluid is used as a low voltage outer electrode instead of a metallic wire mesh. This fluid is in direct contact with the lamp envelope which acts as a two-fold advantage. First, the fluid acts as a strong built-in cooling source. This allows the lamp to be driven at high voltage without forced cooling. Second, the replacement of the wire mesh as the outer electrode by fluid as well as the sleeve eliminates the absorption of radiation from the outer surface of the said DBD-driven light source which more than doubles the efficiency of the DBD-driven light source. The inner high voltage electrode remains in the center of the coaxial tube assembly and provides high voltage across the gas to generate excimer formation.

Abstract: A field emission device having bundles of aligned parallel carbon nanotubes on a substrate. The carbon nanotubes are oriented perpendicular to the substrate. The carbon nanotube bundles may be up to 300 microns tall, for example. The bundles of carbon nanotubes extend only from regions of the substrate patterned with a catalyst material. Preferably, the catalyst material is iron oxide. The substrate is preferably porous silicon, as this produces the highest quality, most well-aligned nanotubes. Smooth, nonporous silicon or quartz can also be used as the substrate. The method of the invention starts with forming a porous layer on a silicon substrate by electrochemical etching. Then, a thin layer of iron is deposited on the porous layer in patterned regions. The iron is then oxidized into iron oxide, and then the substrate is exposed to ethylene gas at elevated temperature. The iron oxide catalyzes the formation of bundles of aligned parallel carbon nanotubes which grow perpendicular to the substrate surface. The height of the nanotube bundles above the substrate is determined by the duration of the catalysis step. The nanotube bundles only grow from the patterned regions.
