Abstract: This application describes a new method for rapid thinning, planarizing and fine polishing surfaces of diamond to the submicron/nanometer level so that large area, uniform thickness diamond wafers can be obtained. The method combines both chemical (dissolution of carbon in molten metals) and mechanical (rotating or moving sample fixtures in contact with the dissolving metals) polishing to achieve flat, smooth surface finishes in a relatively short period of time, thus improving the quality and economics of the overall polishing process. Several embodiments of apparatus for performing such chemical-mechanical polishing (CMP) of diamond are described.

Abstract: The present invention provides improved methods for making field emission devices by which one can pre-deposit and bond the diamond particles or islands on a flexible metal foil at a desirably high temperature (e.g., near 900.degree. C. or higher), and then subsequently attach the high-quality- emitter-coated conductor foil onto the glass substrate. In addition to maximizing the field emitter properties, these methods provide high-speed, low-cost manufacturing. Since the field emitters can be pre-deposited on the metal foil in the form of long continuous sheet wound as a roll, the cathode assembly can be made by a high-speed, automated bonding process without having to subject each of the emitter-coated glass substrates to plasma heat treatment in a vacuum chamber.

Abstract: In accordance with the invention, a field emission device is made by disposing emitter material on an insulating substrate, applying masking particles to the emitter material, applying an insulating film and a gate conductor film over the masking particles and emitter material and removing the particles to reveal a random distribution of apertures to the emitter material. 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.

Exemplary embodiments comprise zone melting and movement of the hot zone through the precursor material. The method can result in superconductive material having improved properties, e.g., higher critical current, as compared to prior art oxide superconductors.

Abstract: A method of producing normal-metal-clad superconductive oxide wire, tape and the like is disclosed. The method comprises forming an intermediate body by surrounding a quantity of the oxide powder (e.g., Ba.sub.2 YCu.sub.3 O.sub.6.9) with an appropriate normal metal jacket, reducing the cross section of the intermediate body by any appropriate technique (e.g., drawing or rolling), and heat treating the elongated body such that substantial sintering of the powder results, and such that, after completion of the heat treatment, the sintered oxide has a composition that is associated with superconductivity in unclad bulk samples of the oxide. The latter condition requires that at least the portion of the cladding that is in contact with the oxide powder is substantially inert with respect to oxygen and the oxide under the conditions of the heat treatment. Silver is the currently preferred inert normal metal. Exemplarily, Ag can be used to provide a diffusion barrier with other normal metal (e.g., Ni and Cu) surrounding the diffusion barrier, or the cladding can consist substantially of Ag. Various techniques for preventing oxygen loss and/or restoring lost oxygen from the powder are disclosed. Advantageously the elongated body is appropriately shaped (e.g., wound into a helical coil) prior to the heat treatment. Elongate bodies produced according to the invention can advantageously be used as superconductive magnets, and in a variety of other apparatus and systems.

Abstract: Devices, systems and techniques are described for producing and implementing articles and materials having nano-scale and microscale structures that exhibit superhydrophobic, superoleophobic or omniphobic surface properties and other enhanced properties. In one aspect, a surface nanostructure can be formed by adding a silicon-containing buffer layer such as silicon, silicon oxide or silicon nitride layer, followed by metal film deposition and heating to convert the metal film into balled-up, discrete islands to form an etch mask. The buffer layer can be etched using the etch mask to create an array of pillar structures underneath the etch mask, in which the pillar structures have a shape that includes cylinders, negatively tapered rods, or cones and are vertically aligned. In another aspect, a method of fabricating microscale or nanoscale polymer or metal structures on a substrate is made by photolithography and/or nano imprinting lithography.
