Evidence of electron-electron interactions around Van Hove singularities of a graphene Moiré superlattice

Si-Yu Li, Ke-Qin Liu, Long-Jin Yin +7

A variety of new and interesting correlated states have been predicted in graphene monolayer doped to Van Hove singularities (VHSs) of its density-of-state (DOS). However, tuning t…
