Abstract: An electron field emission device is provided by placing a substrate in a reactor, heating the substrate and supplying a mixture of hydrogen and a carbon-containing gas to the reactor while supplying energy to the mixture of gases near the substrate for a time to grow a carbon-based body to a thickness greater than 20 micrometers, subsequently removing the substrate and then applying an electrical contact to one surface of the body. The device is free-standing and can be used as a cold cathode in a variety of electronic devices such as cathode ray tubes, amplifiers and traveling wave tubes. The surface of the substrate may be patterned before growth of the carbon-based body to produce a patterned surface on the field emission device after the substrate is removed.

Abstract: 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 favorable 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.
