[20a-P4-20] Oxidation of Cu through a Simply Modified Process and Its Effect for Graphene Nucleation in Atmospheric CVD
Keywords:graphene,chemical vapor deposition,nucleation
Graphene grown by chemical vapor deposition (CVD) is generally polycrystalline where degrade its high carrier mobility by domain boundaries. Therefore, large-size graphene growth by suppressing nucleation is necessary for its electro/optic applications. Here we report that Ar annealing just before growth process in atmospheric CVD provide effective suppression of graphene nucleation.
