Title:
電子放出膜および電界電子放出装置
Document Type and Number:
Japanese Patent JP5011619
Kind Code:
B2
Abstract:
An electron emission film capable of enhancing or suppressing electron emitting characteristics at part of an electron emitting surface, and an electric field electron emission device. Many single-wall carbon nanotubes each having a slender crystal structure are arranged at the center of a CNT film (13) in such a posture as to project almost vertically with respect to the film surface. That is, a fiber structure at a specific surface (raised surface (14)) is oriented vertically to promote electron emission, or a fiber structure is made flat by an action of surface tension to suppress electron emission from a specific surface. For example, the edge portion of a CNT film, which is an area from which electrons are emitted curvedly, is rendered a flat-hair surface (15).
