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.

What is claimed is: 1. A method of improving current density for a carbon nanotube (CNT) emitter source, said method comprising the steps of: (a) forming a conductive layer onto a substrate; (b) forming a CNT layer onto said conductive layer by screen-printing a CNT paste comprising CNT, a binder and a solvent, through a patterned screen; (c) heating said CNT layer for a time sufficient to dry said CNT layer; (d) heating said CNT layer to a temperature and for a time sufficient to effectively volatilize said binder; (e) attaching a film onto said CNT layer; and (f) removing said film. 2. The method of claim 1 wherein said film is an adhesive film. 3. The method of claim 1 wherein a portion of said CNT layer is removed so as to expose a new surface of said CNT layer in which a portion of CNT in said new surface protrudes from said new surface.
