Abstract: This invention provides compositions of matter that contain an electron emitting substance and an expansion material. The expansion material may, for example, be an intercalation compound. When a film is formed from the composition, expansion of the expansion material typically causes rupturing or fracturing of the film. No further treatment of the surface of the film is typically required after expansion of the expansion material to obtain good emission properties. A surface formed from such a fractured film acts as an efficient electron field emitter and thus is useful in vacuum microelectronic devices.

Abstract: A stable cold field electron emitter is produced by forming a coating on an emitter base material. The coating protects the emitter from the adsorption of residual gases and from the impact of ions, so that the cold field emitter exhibits short term and long term stability at relatively high pressures and reasonable angular electron emission.

Abstract: A carbon fiber for a field electron emitter has a coaxial stacking morphology of truncated conical tubular graphene layers, each of which includes a hexagonal carbon layer and has a large ring end and a small ring end at opposite ends in the axial direction. The edges of the hexagonal carbon layers are exposed on at least part of the large ring ends. Since all the exposed edges function as electron emission tips, a large amount of emission current can be obtained.
