我们考虑一个由两个共面均匀带电的纳米盘组成的纳米系统，它们通过库仑力耦合。这种模型代表了二维电子半导体量子点系统的典型情况。我们提供了两个共面纳米片之间的相互作用能作为其分离距离函数的精确积分表达式。我们发现标准库仑势与电流库仑势之间的差具有使人联想到伦纳德-琼斯相互作用势的特征。所得结果可用于理解含有电子的共面带电纳米盘系统中团簇和/或聚集体的形成。(c) 2018作者。
We consider a nanosystem consisting of two coplanar uniformly charged nanodisks that are coupled via Coulomb forces. Such a model represents a typical situation encountered in two-dimensional semiconductor quantum dot systems of electrons. We provide an exact integral expression for the interaction energy between the two coplanar nanodisks as a function of their separation distance. It is found that the difference between a standard Coulomb potential and the current one has features reminiscent of a Lennard-Jones interaction potential. The results derived can be useful to understand formation of clusters and/or aggregates in systems of coplanar charged nanodisks that contain electrons. (c) 2018 Author(s).
