We report on co-existing dual anisotropy ripple formation, sp bonding transformation, and variation in the delocalized π electron system in 1 keV Ar+ ion irradiated few-layer graphene surfaces. Ripples in directions, perpendicular and parallel to the ion beam were found. The irradiation effect and ... [Appl. Phys. Lett. 101, 213107 (2012)] published Wed Nov 21, 2012.
