    Abstract: A field emission cathode comprises a glass substrate in combination with an insulating layer sandwiched between two conducting layers functioning as electrodes. Cavities extending through one of the electrodes and the insulating layer to the surface of the other electrode contain highly compacted and porous electron emissive layers which provide high electrical resistance between said electrodes and are diffused with metallic gold to form needle-shaped metal deposits on the surface as well as within the emissive layers. Such cathodes are used in image converters and image display tubes.

    Abstract: A field emission cathode plate is disclosed, which includes: a substrate; a cathode layer, disposed on the substrate; a conductive layer with an arc surface or a resistor layer with an opening and resistivity larger than that of the cathode layer, disposed on the cathode layer; and a cambered field emission layer, having an arc surface and disposed on the conductive layer or on the cathode layer in the opening of the resistor layer and covering the resistor layer around the opening. The present invention also provides a method for fabricating the above-mentioned field emission cathode plate. The method can provide field emission cathode plate achieving uniform field emission and does not involve high resolution and cost.

    Abstract: A method of operating and process for fabricating an electron source. A conductive rod is covered by an insulating layer, by dipping the rod in an insulation solution, for example. The rod is then covered by a field emitter material to form a layered conductive rod. The rod may also be covered by a second insulating material. Next, the materials are removed from the end of the rod and the insulating layers are recessed with respect to the field emitter layer so that a gap is present between the field emitter layer and the rod. The layered rod may be operated as an electron source within a vacuum tube by applying a positive bias to the rod with respect to the field emitter material and applying a higher positive bias to an anode opposite the rod in the tube. Electrons will accelerate to the charged anode and generate soft X-rays.

    Abstract: Electron emitters and a method of fabricating emitters are disclosed, having a concentration gradient of impurities, such that the highest concentration of impurities is at the apex of the emitters and decreases toward the base of the emitters. The method comprises the steps of doping, patterning, etching, and oxidizing the substrate, thereby forming the emitters having impurity gradients.

    Abstract: In one aspect, the invention encompasses a method of treating the end portions of an array of substantially upright silicon-comprising structures. A substrate having a plurality of substantially upright silicon-comprising structures extending thereover is provided. The substantially upright silicon-comprising structures have base portions, and have end portions above the base portions. A masking layer is formed over the substrate to cover the base portions of the substantially upright silicon-comprising structures while leaving the end portions exposed. The end portions are then exposed to conditions which alter the end portions relative to the base portions. In another aspect, the invention encompasses a method of treating the ends of an array of silicon-comprising emitter structures. A substrate having a plurality of silicon-comprising emitter structures thereover is provided. The emitter structures have base portions and ends above the base portions. A layer of spin-on-glass is formed over the substrate. The layer of spin-on-glass covers the base portions of the emitter structures and leaves the ends exposed. The ends are then exposed to conditions which alter the ends relative to the base portions. In yet another aspect, the invention encompasses a cathode assembly which includes a plurality of silicon-comprising emitter structures projecting over a substrate. The emitter structures have base portions and ends above the base portions, and the ends comprise a different material than the base portions.
