Calculation of the potential energy between copper and carbon atoms in growth of graphene on copper substrate by CVD method

In this paper, we obtained analytic calculation of graphene nanostructure potential in formation and growth by CVD on Cu layer and analyzing of bonding between copper and Carbon atoms in the first deposited layer. Studies show that the growth of graphene on Cu due to the very low solubility of carbon in copper can cause uniform deposition of high-quality and large-area single-layer graphene and so known Cu as the better catalyst The reaction between carbon molecules and atoms of copper with perturbation theory solved, Thus, we suggest carbonmolecules with sp2 hybrid orbitals offerח cloud overlap to 4s orbital copper atom. We analyzed this chemical potential which is due to copper, calculated vertical circular potential, and for Carbon dimers hyperbolic parabola potential .
