<p>An electron emission source and a field emission device using the same. The diamond-like carbon (DLC) film used as the electron emission source is featured by its film structures formed on the substrate surface arranged in a petal pattern. The height of the DLC flake is in micro scale and the thickness of the flake is in nano scale. The disclosed DLC flake film has a high aspect ratio. Hence, the DLC film has a good enhancing factor favourable for field emission, acting as a good electron-emitting source. In addition, the electron-emitting source material disclosed can be applied in a field emission display to act as a stable electron-emitting source.</p> |
