摘要：
In the present invention an electron-emitting material is provided wherein the field emission initiation voltage or work function is smaller than that of conventional materials. That is, the present invention relates to an electron-emitting sheet material which is a material comprising a substrate 102 and a graphite sheet 101 laminated on the top of the substrate 102, wherein (1) the graphite sheet 101 has a layered structure of layers of graphenes consisting of a plurality of carbon hexagonal networks, (2) the graphenes are layered relative to one another so that the c-axial direction of each graphene is substantially perpendicular to the plane of the substrate 102, (3) the graphite sheet 101 is laminated on top of the substrate 102 so that the c-axial direction of each graphene is substantially perpendicular to the plane of the substrate 102, and (4) the graphite sheet 101 comprises an element other than carbon as a second element.
