    Abstract: The present invention relates generally to a new integrated Vacuum Microelectronic Device (VMD) and a method for making the same. Vacuum Microelectronic Devices require several unique three dimensional structures: a sharp field emission tip, accurate alignment of the tip inside a control grid structure in a vacuum environment, and an anode to collect electrons emitted by the tip. Also disclosed is a new structure and a process for forming diodes, triodes, tetrodes, pentodes and other similar structures. The final structure made can also be connected to other similar VMD devices or to other electronic devices.

    Abstract: An electron device including a diamond material electron emitter and an anode, both disposed on a supporting substrate, so as to define an interelectrode region therebetween. Electron transport across the interelectrode region is initiated at an emitting surface of the diamond material electron emitter. An alternative embodiment employs a gate electrode disposed substantially symmetrically and axially displaced about the electron emitter and substantially in the interelectrode region to provide a modulation capability.

    Abstract: A method of fabricating a double-tapered scanning tunneling microscope comprises (a) immersing one end of the tip in a bath of an acidic aqueous etchant solution containing an alkaline earth salt, with the wire positioned substantially perpendicularly to the surface of the solution; and (b) etching the wire at about 25 volts root mean squared (rms) alternating current (ac) until a double-tapered tip is formed thereon. The etching step is preferably followed by a polishing step which comprises (c) providing a thin film of a second acidic aqueous etchant solution containing an alkaline earth salt; then (d) contacting said electrode tip to the thin film: and then (e) etching the tip at about 2 volts rms ac to thereby polish the tip.Also disclosed is a method of inhibiting the formation of carbon on a scanning tunneling microscope tip which comprises (a) positioning a wire in an etchant solution and then (b) etching the wire while excluding carbon dioxide therefrom.Double-tapered scanning tunneling microscope tip comprises of an elongate wire and methods of using the same are also disclosed.

    Abstract: Ultrasharp polycrystalline diamond edges, points, and improved diamond composites of predetermined configuration usable as cutting instruments, as high intensity sources for the emission of electrons, ions, neutrons, x-rays, coherent and incoherent light and high frequency electromagnetic radiation, and as ultraprecision molded mechanical and optical parts, or as high field permanent magnets or electrets, are produced by preparing and classifying natural and synthetic ultrafine uniform graphite particles, preferably of the rhombohedral phase, which are directly converted into diamond particles having a particle size of 3 to 100 angstroms, placing the ultrafine powder, either before or after the synthesis, with or without suitable additives, in a diamond mold defining the ultrafine edge or form to be produced, and applying a pressure of the order of 80 to 90 kb, preferably dynamic or static ultrahigh pressures of 100 to about 1000 kb, while heating the powder to a temperature of the order of 2440.degree. K. to 2500.degree. K., or preferably in the range of 2500.degree. to 3000.degree. K., in an ultrahigh vacuum or inert atmosphere after degassing to remove contaminants and avoid oxidation of the diamond powder. The requisite dimensional tolerances of the order of 10 to 100 angstroms are reproducibly obtained by final electron beam glazing and annealing using liquid helium systems with superconducting lenses of special design.
