Abstract

The influence of orientation of copper crystal on the processes of methane decomposition and the growth of graphene layers is studied in this paper. It is shown that crystal nucleus growth rate and coating formation rate are different on copper grains with different crystal orientation. Maximum coating formation rates are recorded for 110 planes. Maximum crystal growth rate and maximum size of graphene single crystals in a film are observed for 100 plane. The difference in the growth rates of the graphene coating is explained by the difference in the kinetics of decomposition of methane and the diffusion rates on surfaces with different crystal orientation.
