Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a field emission type electrode capable of comparatively uniforming electron emission density. SOLUTION: After applying a humidifying treatment on a field emission type electrode with an electron emission film formed, a pulse voltage is impressed between the field emission type electrode and an opposed electrode. Water molecules adhered on the electron emission film repeats absorption and desorption in correspondence to the pulse voltage. With this, electron begins to be emitted from an area with weak electron emission intensity and an area in which electron is not emitted, so that unevenness of electron emission density of the field emission type electrode can be comparatively averaged out.

PROBLEM TO BE SOLVED: To uniformly form carbon fiber having good characteristics on a substrate. SOLUTION: In this carbon fiber manufacturing method, a laminate of a first catalyst material and a catalyst particle containing a second catalyst material is disposed on the substrate, and a catalyst particle comprising the first catalyst material and the second catalyst material is formed on the substrate by reacting the first catalyst material with the second catalyst material. After that, the carbon fiber is grown on the substrate by reacting the catalyst particle comprising the first catalyst material and the second catalyst material with the raw material of the carbon fiber.

Abstract:
Provided are electron emitters based upon diamondoid monolayers, preferably self-assembled higher diamondoid monolayers. High intensity electron emission has been demonstrated employing such diamondoid monolayers, particularly when the monolayers are comprised of higher diamondoids. The application of such diamondoid monolayers can alter the band structure of substrates, as well as emit monochromatic electrons, and the high intensity electron emissions can also greatly improve the efficiency of field-effect electron emitters as applied to industrial and commercial applications.
