Abstract

âº We observed and tuned the oxidation states of graphene by applying the potential. âº We show that atomic oxygen reversibly binds to less defective single-layer graphene. âº Oxidation of graphene was tuned by migration of oxygen ions. âº First-principles DFT calculations suggest two grapheneoxygen bonding configurations.
