Title:
FIELD EMISSION ELEMENT HAVING CARBON NANO-TUBE COVERED BY PROTECTION FILM
Document Type and Number:
Japanese Patent JP2003217516
Kind Code:
A
Abstract:
To provide a field emission element having carbon nano-tube covered by protection film.
The field emission element is constructed by a substrate 11, a negative electrode 12 laminated of the substrate 11, carbon nano-tubes 13 formed to the negative electrode 12, and protection films 15 formed so as to wrap the top end part of respective carbon nano-tubes. The protection film 15 is constructed by one kind of substance chosen from nitride group substances, carbide group substances, or oxide group substances. By the above, as the carbon nano-tube 13 is protected by the protection film 15, the damage caused by arcing or residual gas is prevented, and the field emission element having stable field emission characteristics is realized.
