Composition for forming electron emission source, electron emission source including the composition, method of preparing the electron emission source, and field emission device including the electron emission source

摘要

An electron emission source includes nano-sized acicular materials and a cracked portion formed in at least one portion of the electron emission source. The acicular materials are exposed between inner walls of the cracked portion. A method for preparing the electron emission source, a field emission device including the electron emission source, and a composition for forming the electron emission source are also provided in the present invention.
