图8. 褶皱对双晶石墨烯晶界5-7环中C---C键预拉伸情况的影响晶界沿锯齿形方向. 在垂直晶界方向和沿晶界方向上应变分量最大的键分别为Bond-I和Bond-II |
Fig. 8. Wrinkle effect on the tensile pre-strain induced via the 5-7 ring of grain boundary (along zigzag direction). Bond-I和Bond-II are the C---C bonds with the maximum tensile pre-strain along the directions perpendicular to and along the grain boundary , respectively |
