    Abstract: An electron source is formed on a silicon substrate having opposing first and second surfaces. At least one field emitter is prepared on the second surface of the silicon substrate to enhance the emission of electrons. To prevent oxidation of the silicon, a thin, contiguous boron layer is disposed directly on the output surface of the field emitter using a process that minimizes oxidation and defects. The field emitter can take various shapes such as pyramids and rounded whiskers. One or several optional gate layers may be placed at or slightly lower than the height of the field emitter tip in order to achieve fast and accurate control of the emission current and high emission currents. The field emitter can be p-type doped and configured to operate in a reverse bias mode or the field emitter can be n-type doped.

    Abstract: A method of manufacturing field-emitter arrays by a molding technique includes uniformly controlling a shape of mold holes to obtain field emitter tips having diameters below 100 nm and blunted side edges. Repeated oxidation and etching of a mold substrate formed of single-crystal semiconductor mold wafers is carried out, wherein the mold holes for individual emitters are fabricated by utilizing the crystal orientation dependence of the etching rate.

    Abstract: A diamond electron source in which a single sharpened tip is formed at one end of a pillar-shaped diamond monocrystal of a size for which resist application is difficult in a microfabrication process, as an electron emission point used in an electron microscope or other electron beam device, and a method for manufacturing the diamond electron source. One end of a pillar-shaped diamond monocrystal 10 is ground to form a smooth flat surface 11, and a ceramic layer 12 is formed on the smooth flat surface 11. A thin-film layer 14 having a prescribed shape is deposited on the ceramic layer 12 using a focused ion beam device, after which the ceramic layer 12 is patterned by etching using the thin-film layer 14 as a mask. A single sharpened tip is formed at one end of the pillar-shaped diamond monocrystal 10 by dry etching using the resultant ceramic mask.

    Abstract: A method of producing field emitters having improved brightness and durability relying on the creation of a liquid Taylor cone from electrically conductive materials having high melting points. The method calls for melting the end of a wire substrate with a focused laser beam, while imposing a high positive potential on the material. The resulting molten Taylor cone is subsequently rapidly quenched by cessation of the laser power. Rapid quenching is facilitated in large part by radiative cooling, resulting in structures having characteristics closely matching that of the original liquid Taylor cone. Frozen Taylor cones thus obtained yield desirable tip end forms for field emission sources in electron beam applications. Regeneration of the frozen Taylor cones in-situ is readily accomplished by repeating the initial formation procedures. The high temperature liquid Taylor cones can also be employed as bright ion sources with chemical elements previously considered impractical to implement.
