CARBON NANOTUBE ELECTRONIC DEVICE AND ELECTRON SOURCE

Title:

CARBON NANOTUBE ELECTRONIC DEVICE AND ELECTRON SOURCE

Document Type and Number:

WIPO Patent Application WO/2002/063693

Kind Code:

A1

Abstract:

An electronic device and an electron source comprising a multilayer carbon nanotube in which electrodes are so constituted as to be connected electrically with a large number of tubular graphene sheets among tubular graphene sheets of the multilayer carbon nanotube arranged concentrically or spirally. Ideally, the electrodes are connected electrically with all tubular graphene sheets. In order to decreas the contact resistance between the electrode and the tubular graphene sheets, the carbon nanotube is cut immediately before fabricating the electrode, or impurities between the electrodes and the tubular graphene sheets are removed and the electrodes are formed of a metal making strong chemical bond with a carbon atom. The contact resistance between the multilayer carbon nanotube and the electrodes can be decreased while decreasing the electrical resistance of the multilayer carbon nanotube.
