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.
Abstract:
A method of preparing an ultra sharp tip, in particular a single atom tip, is provided, comprising providing a tip (11) having a shank (15), an apex (16), and a coating (14,17,18) covering the shank and the apex; locally removing the coating (14) from the apex (16) by field evaporation; and partially or fully restoring the coating at the apex (16).
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.
