Abstract
A field emission cold cathode utilizes a film of carbon flake field emitters deposited thereon. The carbon flakes may exhibit rolled edges, but are still sufficient to provide improved field emission characteristics. A cold cathode using such carbon flake field emitters can be utilized to produce afield emission flat panel display, which can be implemented for use with a computer system.
