Based on first-principles calculations, electronic properties of edge-functionalized zigzag graphene nanoribbons (ZGNRs) on SiO2 substrate are presented. Metallic or semiconducting properties of ZGNRs are revealed due to various interactions between edge-hydrogenated ZGNRs and different SiO2(0001) surfaces. Bivalent functional groups decorating ZGNRs serve as the bridge between active edges of ZGNRs and SiO2(.) These functional groups stabilize ZGNRs on the substrate, as well as modify the edge states of ZGNRs and further affect their electronic properties. Bandgaps are opened owing to edge state destruction and distorted lattice in ZGNRs.
