利用角分辨光电能谱研究了在台阶Ni（771）表面制备的石墨烯结构的碳纳米带。电子结构是各向异性的：平行于条纹方向，石墨型分散体进行测量，而垂直方向显示两个纠缠带结构相对于彼此的能量转移。这些被实验确定为超晶格引起的微表面中心带结构及其umklapp散射图像。
Carbon nanostripes of graphene structure prepared on the stepped Ni(771) surface have been studied by angle-resolved photoemission. The electronic structure is anisotropic: parallel to the stripe direction, a graphite-type dispersion is measured, whereas the perpendicular direction displays two entangled band structures shifted in energy with respect to each other. These are experimentally identified as the microsurface-centered band structure and its umklapp scattered image caused by the superlattice.
