Abstract:
PROBLEM TO BE SOLVED: To provide a carbon film for a field emission device utilized for manufacture of a flat cathode, provided with specific physical characteristics. SOLUTION: The carbon film (703) used as a field emission cathode is a thin carbon film formed on a substrate (803). The carbon film has a UV-Raman band ranging between 1578 cm -1 and 1620 cm -1 with a full width at half maximum (FWHM) of 25 to 165 cm -1 . The carbon film may be thinner than 300 nanometers. The substrate on which the film is deposited may or may not have conductivity. In case that the substrate does not have conductivity, the substrate can be coated by a continuous conductive layer, or by a minute net structure of a conductive material.

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.
