Abstract (en)

The electron emission source includes a substrate and an electron emission layer formed on the substrate. The electron emission layer includes a composition of diamond-like carbon (DLC) film structures. The height of the DLC flakes is in micrometer scale, and the thickness of the DLC flakes is in nanometer scale. Hence, the aspect ratio of the DLC film structures is high. Therefore, the DLC film can be used as a good electron emission source. A conductive layer can be optionally deposited on the surface of the substrate for further enhancing DLC film in electron emission.
