(color online) Calculated energy pathway (solid line) along which an F2 molecule diffuses from molecular state to dissociative state (DF2); and the distance (dashed line) from the geometric center of the F2 molecule to the graphene surface, denoted as . Configuration is abbreviated as cfg, and graphene is abbreviated as Gr.
