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.
Claims5
A method for improving the emission current of a field emitter device that comprises an electron field emitter comprising carbon nanotubes on a surface, comprising
- applying a liquid material to the surface;
- heating the liquid material to form a material having adhesive contact with the surface;
- and
- separating the adhesive material from the surface.
