摘要： A field emission device may comprise: an emitter comprising a cathode electrode and an electron emission source supported by the cathode electrode; an insulating spacer around the emitter, the insulating spacer forming an opening that is a path of electrons emitted from the electron emission source; and/or a gate electrode around the opening. The electron emission source may comprise a plurality of graphene thin films vertically supported in the cathode electrode toward the opening.
