Strain-Induced Orientation-Selective Cutting of Graphene into Graphene Nanoribbons on Oxidation† Liang Ma1, Prof. Jinlan Wang1,*, Dr. Feng Ding2 ![]() Cut to ribbons: Making atomically well controlled graphene nanoribbons (GNRs) is prerequisite for many graphene applications. Ab initio calculations reveal that, on applying a uniaxial external tensile strain, O atoms adsorbed on graphene form parallel epoxy chains, and subsequent cutting by oxygen attack gives GNRs instead of the quantum dots that are obtained from unstrained graphene . http://good.gd/1876043.htm |
