Alexander I. Zhbanov, Evgeny G. Pogorelov, Yia-Chung Chang

摘要:

给出了碳纳米管间范德华势能和作用力的解析表达式。两个碳原子的Lennard-Jones势和LA提出的涂抹近似方法Girifalco被使用。精确公式用有理函数和椭圆函数表示。计算了碳纳米管的电势和力。绘制了单壁和多壁纳米管的均匀电势曲线.平衡距离,最大吸引力,和势能已估计。

英文摘要:

The analytical expressions for the van der Waals potential energy and force between two crossed carbon nanotubes are presented. The Lennard-Jones potential for two carbon atoms and the method of the smeared out approximation suggested by L.A. Girifalco were used. The exact formula is expressed in terms of rational and elliptical functions. The potential and force for carbon nanotubes were calculated. The uniform potential curves for single- and multi- wall nanotubes were plotted. The equilibrium distance, maximal attractive force, and potential energy have been estimated.
