Abstract

The elastic interaction of quantum disks (QDs) in a nanowire (NW), i.e., in a hybrid QD/NW structure with sharp heterointerfaces, is considered for the first time. Within the framework of the defect micromechanics approach, the energy of QD pair interaction is established and it is demonstrated that for QDs with a lattice misfit of the same sign, a zone of attraction to each other appears, depending on the ratio of the QD axial size to the NW radius. The discovered effect should be taken into account when choosing the modes of formation of hybrid QD/NW structures and in models explaining their properties.

混合 QD/NW 结构中量子盘的弹性相互作用

摘要首次考虑了量子盘（QDs）在纳米线（NW）中的弹性相互作用，即在具有尖锐异质界面的 QD/NW 混合结构中的相互作用。在缺陷微观力学方法的框架内，建立了 QD 对相互作用的能量，并证明了对于具有相同符号晶格错配的 QD，会出现一个相互吸引的区域，这取决于 QD 轴向尺寸与 NW 半径之比。在选择混合 QD/NW 结构的形成模式和解释其特性的模型时，应考虑到所发现的效应。
