▎ 摘　　要

NOVELTY - A composition comprises a substrate, a metal oxide formed on the substrate, and graphene (10 ml) formed on the metal oxide. USE - As composition for controlled growth of graphene monolayers on a metal oxide surface, used in semiconductor logic device or spintronic device (claimed). ADVANTAGE - The graphene monolayers are continuous, well ordered and in registry with each other. The graphene lacks a significant band gap. The method enables growth of up to three, four, five or even six-ten monolayers of graphene on similar important metal oxides including nickel oxide, cobalt oxide and chromium oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for controlled growth of graphene monolayers on a metal oxide surface, involving depositing carbon on a surface of the metal oxide by molecular beam epitaxy of carbon for a period of time sufficient to grow the graphene monolayers.
