Abstract

A multi-wall carbon nanotube field emitter and method of producing the same is disclosed The multi-wall carbon nanotube field emitter comprises a nanotube having a diameter between approximately 1 nanometer and approximately 100 nanometers with an integrally attached outer layer of graphitic material that is approximately 1 micrometer to approximately 10 micrometers in diameter attached to an etched tip of a wire. The tip of the wire is etched to form a tip and a slot is fabricated in the tip for alignment and attachment of the carbon nanotube. A focus ion beam is used to weld the nanotube to the tungsten tip for electron field emission applications.
