| Outline of Final Research Achievements |
In this study, we aimed to synthesize a diamond thin film as a functional carbon thin film from charcoal feedstock by using novel high-pressure hydrogen plasma without ultrahigh pressure and temperature process conditions. As a result, it was found that methane was mainly generated through the chemical reaction between hydrogen plasma and charcoal. Furthermore, the generated gas species is independent on plasma parameter, as far as the glow discharge was maintained. The mineral component contained in the charcoal remains on the charcoal surface after hydrogen plasma etching. Therefore, it was revealed that the proposed deposition method has a refinement effect of carbon feedstock. At the present stage, because the graphite-like film can be obtained by the proposed method, it can be found that this method has potential to prepare the graphene film.
