Flat band and Lifshitz transition in long-range-ordered supergraphene obtained by Erbium intercalation
We report the observation of graphene doped up to the Lifshitz transition obtained solely by the intercalation of Erbium atoms. ARPES measurements show that a wide flat band is generated around the M point of the Brillouin zone. We propose that this is the effect of an induced spin-orbit coupling. S...
