The stability of graphene band structures against an external periodic perturbation; Na on Graphene

We report that the \(\pi\) band of graphene sensitively changes as a function of an external potential induced by Na especially when the potential becomes periodic at low temperature. We have measured the band structures from the graphene layers formed on the 6H-SiC(0001) substrate using angle-resol...
