石墨微球间的范德华相互作用
van der Waals interactions between graphitic nanowiggles
摘要：
用耦合偶极子方法计算了两个平行的石墨微球之间的范德华相互作用。通过考虑离散的原子结构，CDM是明确确定这种相互作用的有效和准确的方法。我们的研究结果表明，范德华力从吸引力到排斥力变化的纳米带沿其长度相对于彼此移动。该特征导致系统在运动过程中的多个稳定和不稳定位置。这些位置可以通过改变GNW的长度来调整。此外，热效应对范德华相互作用的影响也进行了广泛的研究。本文的工作为今后的理论和实验研究提供了有益的指导。
英文摘要：
The van der Waals interactions between two parallel graphitic nanowiggles (GNWs) are calculated using the coupled dipole method (CDM). The CDM is an efficient and accurate approach to determine such interactions explicitly by taking into account the discrete atomic structure. Our findings show that the van der Waals forces vary from attraction to repulsion as nanoribbons move along their lengths with respect to each other. This feature leads to a number of stable and unstable positions of the system during the movement process. These positions can be tuned by changing the length of GNW. Moreover, the influence of the thermal effect on the van der Waals interactions is also extensively investigated. This work would give good direction for both future theoretical and experimental studies.
