Interfacial Bonding Of Plating Al On Graphene Surface Through Organic Aluminum Reduction

Graphene (Gr) was plated with an Al layer by using an organic aluminum reduction method, and the total adsorption energy and the optimum adsorption location of Al atom on the Gr surface were studied. The interface of the Al/Gr/Al double-interface model was tightly bonded with the Gr layer, and the interface structure was stable. The total adsorption energy of the Al atoms at the central H point of Gr hexagonal lattice was the highest. The Al atoms at C-C bond bridge midpoint B and above C atom T point tended to shift toward the H point, and thus, the H point was the best adsorption site for the Al atoms on the Gr surface.
