How to fabricate a semihydrogenated graphene sheet? A promising strategy explored

There has been a long-standing dream to synthesize a semihydrogenated graphene sheet. Here, we propose a promising strategy based on physical method instead of chemical method to avoid the current problems in synthesizing. By applying pressure on a fluorinated BN sheet supported on a graphene sheet, we can induce a structural transition for H atoms jumping from the graphane sheet to fluorinated BN sheet, thus transforming the graphane sheet to a graphone sheet. Moreover, hole doping can reduce the pressure required for such structural transition. This strategy is more feasible and controllable as compared to the existing experimental techniques.
