Energy path for the formation of graphene nuclei.

a, The energy landscape for the sequential formation of graphene nuclei on a γ-Al2O3 substrate. Ec and Es represent the overall activation barriers for nucleus growth at different temperatures. b, Minimum energy path for the formation of graphene nuclei. The inset shows the result of the most stable state of a C adatom on the surface of a γ-Al2O3 substrate.
