Band structure tuning of doped Graphene/hBN heterostructure

Tuning Dirac electrons by a periodic potential is an important scientific question and graphene/h-BN is a model van der Waals heterostructure for investigating this. Here we report our recent ARPES progress on the electronic band structure of doped graphene/BN, which shows intriguing band structure engineering of both the valence and conduction bands.
