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…

Direct experimental evidence of pi magnetism of a single atomic vacancy in graphene
Yu Zhang, Si-Yu Li, Wen-Tian Li +4
The pristine graphene is strongly diamagnetic. However, graphene with single carbon atom defects could exhibit paramagnetism with local magnetic moments ~ 1.5 per vacancy1-6. Theor…
