Organometallic hexahapto (η6)-chromium metal complexation of single-layer graphene, which involves constructive rehybridization of the graphene π-system with the vacant chromium dπ orbital, leads to field effect devices which retain a high degree of the mobility with enhanced on-off ratio. This η6 mode of bonding is quite distinct from the modification in electronic structure induced by conventional covalent σ-bond formation with creation of sp3 carbon centers in graphene lattice and this chemistry is reversible.
