Electron emissive film |
摘要 |
An electron-emissive film (170, 730) is made from graphite and has a surface defining a plurality of emissive clusters (100), which are uniformly distributed over the surface. Each of the emissive clusters (100) has dendrites (110) extending radially from a central point (120). Each of the dendrites (110) has a ridge (130), which has a radius of curvature of less than 10 nm. The graphene sheets (160) that form the dendrites (110) have a (002) lattice spacing within a range of 0.342-0.350 nanometers.
