Hydrogenation of a few layer graphene is known to result in the change of sp2 to sp3 hybridization, which can be exploited to grow nanodiamond thin films. First-principles studies of hydrogenated monolayer, bilayer, and tri-layer graphene, supported on Ni(111) substrate are performed using first-principles density functional theory. The monolayer graphene and AB-stacked bilayer graphene are shown to rehybridize to form sp3 bonds, thus promoting the formation of nanodiamond thin films. Structural, electronic and magnetic properties of the hydrogenated monolayer, bilayer, and tri-layer graphene are discussed.
