Abstract

Abstract : The reversible migration of adatoms along a basal plane of graphene under electrical bias is experimentally demonstrated. Single‐layer graphene oxide with partial oxygen adatom coverage is utilized for this demonstration. The intensity ratio of G and G′ Raman modes is used to determine the oxygen adatoms migration. Finally, reversible wettability property of graphene due to oxygen adatom migration is demonstrated.
