    摘要： A method and system for manufacturing a field emission cathode having enhanced electron emission properties. The field emission cathode is prepared by providing a field emission substrate, an alkali metal alloy is formed at and below the exposed surface of the substrate, and a surface layer of alkali metal atoms are formed on the exposed surface by Gibbsian diffusion segregation action. If the monolayer, or surface layer, is desorbed, the diffusion action reestablishes the alkali metal surface layer thereby providing a stable alkali metal layer and enhanced electron emission characteristics.

    摘要： A monolithically integrated 3-D membrane or diaphragm/tip (called 3-D tip) of substantially all UNCD having a tip with a radius of about less than 50 nm capable of measuring forces in all three dimensions or being used as single tips or in large arrays for imprint of data on memory media, fabrication of nanodots of different materials on different substrates and many other uses such as nanolithography production of nanodots of biomaterials on substrates, etc. A method of molding UNCD is disclosed including providing a substrate with a predetermined pattern and depositing an oxide layer prior to depositing a carbide-forming metallic seed layer, followed by seeding with diamond nano or micropowder in solvent suspension, or mechanically polishing with diamond powder, or any other seeding method, followed by UNCD film growth conforming to the predetermined pattern. Thereafter, one or more steps of masking and/or etching and/or coating and/or selective removal and/or patterning and/or electroforming and/or lapping and/or polishing are used in any combination to form the tip or probe.

    摘要： A flat panel display includes a ferroelectric thin film between first and second spaced apart electrodes. The ferroelectric thin film emits electrons upon application of a predetermined voltage between the first and second spaced apart electrodes. The electrons are emitted in an electron emission path and impinge upon a luminescent layer such as a phosphor layer, which produces luminescence upon impingement upon the emitter electrodes. The ferroelectric thin film is preferably about 2 .mu.m or less in thickness and is preferably a polycrystalline ferroelectric thin film. More preferably, the thin ferroelectric film is a highly oriented, polycrystalline thin ferroelectric film. Most preferably, highly oriented ferroelectric thin film has a preferred (001) crystal orientation and is about 2 .mu.m or less in thickness. A flat panel display may be formed of arrays of such display elements. Top and bottom electrodes or side electrodes may be used. The display may be formed using conventional microelectronic fabrication steps.
