Abstract: A field emission device in which a protective material is employed in relation to the anode wherein the protective material is selected from one or more members of the group consisting of amorphous carbon, graphite, diamond-like carbon, fullerenes, carbon nanotubes, a (co)polymer and an organic coating compound.

Abstract: This invention relates to the electrochemical deposition of carbon nanotubes (“CNTs”) on a substrate using an electrochemical cell. A dispersion of a complex of CNTs and an anionic polymer is neutralized and thereby caused to deposit on the anode plate of the cell.

Abstract: This invention provides a process for improving the field emission of an electron field emitter comprised of an acicular emitting substance such as acicular carbon, an acicular semiconductor, an acicular metal or a mixture thereof, comprising applying a force to the surface of the electron field emitter wherein the force results in the removal of a portion of the electron field emitter thereby forming a new surface of the electron field emitter.

Abstract: Alloyed nanophenes comprising carbon, boron, and a Group V element other than nitrogen are provided. The alloyed nanophenes are useful, for example, as miniature electronic components, such as wires, coils, schottky barriers, diodes, inductors, memory elements, and other circuit devices and elements.

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: This invention provides an electron field emitter and field emitter cathode comprised of carbon fibers grown from the catalytic decomposition of carbon-containing gases over small metal particles. Each carbon fibers has graphene platelets arranged at an angle with respect to the fiber axis so that the periphery of the carbon fiber consists essentially of the edges of the graphene platelets. These field emitters and field emitter cathodes are useful in computer, television and other types of flat panel displays.
