▎ 摘  要

The atomic structure, electron distribution, work function, and band structure of closed edge graphene are investigated with density functional theory. Field emission performance of closed edge graphene is compared with that of open edge graphene. We provide a possible explanation for the field emission microscopy image change after high emission current, which appeals to the experimentalists for further investigation.
