Abstract
Patterned ion-bombarded carbon electron emitters and the processes for producing them. The electron emitters are produced by forming a layer of composite of carbon particles and glass on a substrate then bombarding the composite with an ion beam. The electron emitters are useful in field emitter cathode assemblies which are fabricated into flat panel displays.
