ABSTRACT:
Carbon cone and carbon whisker field emitters are disclosed. These field emitters find particular usefulness in field emitter cathodes and display panels utilizing said cathodes. The carbon cone and carbon whisker field emitters can be formed by ion beam bombardment (e.g., ion beam etching) of carbon materials (e.g., bulk carbon, carbon films or carbon fibers).
