Possible stably-ordered substitutional structures based on a graphene-typecrystal lattice are considered. A kinetic model of atomic ordering inmetal-doped graphene with stoichiometric (1/8, 1/4, 1/2) and nonstoichiometriccompositions is developed. Inasmuch as the intrasublattice and intersublattice'interchange' ('mixing') energies are competitively different forgraphene-based lattice, kinetic curves of the long-range order (LRO) parametersmay be nonmonotonic for the structures described by two or three LROparameters.
