The ab-initio study of diamond growth on its (111) surface

The adsorption of carbon on Ni (111) surface is studied with density functional theory in this paper. The adsorption energy and density of states is calculated. We analyzed the density of states of carbon on diamond (111) surface and carbon adsorbed on Ni (111) surface, the result shows that they have similar electronic structure, namely, they both have nonbonding and bonding spa hybridized electrons. Furthermore, it is found that the carbon atoms on diamond ( 111) surface and those adsorbed on Ni (111) surface are prone to bonding and form a diamond-like structure.
