▎ 摘　　要

NOVELTY - A graphene-based field emission cold cathode, comprises a conductive substrate and a graphene film layer, which is an emitter of the cathode, where conductive substrate layer is closely contacts with the graphene film. USE - Graphene-based field emission cold cathode for use as electron source for field emission display and other fields. ADVANTAGE - The cathode has low electric field, low threshold electric field and large emission current. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene-based field emission cold cathode.
