| Outline of Final Research Achievements |
(1) Confirmation of oxidation resistance of graphene and catalysts oxidation using H2O: Oxidation rate on graphene (Gr)/Cu substrates decreases compared with it on Cu surfaces. This is because graphene plays a role of barrier layer for oxygen and O2 cannot reach Gr/Cu interface. For fast oxidation of Gr/Cu substrates, H2O is proposed as oxidant in behalf of O2.
(2) Finding of the stopping power of Cu2O films for C atom diffusion: It was found that Cu2O films can intercept the C atom diffusion into Cu bulk substrate. Using this knowledge, high quality graphene can be grown on Cu2O/Cu substrates.
