外界条件对卷曲石墨烯边缘结构的影响

Effect of external conditions on the structure of scrolled graphene edges

M. M. Fogler, A. H. Castro Neto, F. Guinea

摘要:

碳纳米卷的特征尺寸-“巴基卷”-通过分析悬浮和衬底沉积的石墨烯样品的代表性模型的弹性、范德华和静电能之间的竞争来计算。结果与原子模拟和实验观察到的螺旋石墨烯边缘是一致的。静电控制的包装被证明是实际可行的,并指出其可能的设备应用。

英文摘要:

Characteristic dimensions of carbon nanoscrolls - "buckyrolls" - are calculated by analyzing the competition between elastic, van der Waals, and electrostatic energies for representative models of suspended and substrate-deposited graphene samples. The results are consistent with both atomistic simulations and experimental observations of scrolled graphene edges. Electrostatic control of the wrapping is shown to be practically feasible and its possible device applications are indicated.
