Localization of carriers in a self-organized quantum dot is a problem of quantum mechanics to be solved with the localizing potential for electrons and holes determined by the geometry, chemical composition, and built-in mechanical stress–strain field. We show that changes in the aspect ratio of a buried pyramidal quantum dot result in a substantial redistribution of the mechanical field components, which in turn provides certain non-trivial conditions for the strongest carrier localization at any given volume of the quantum dot.

自组织量子点中的载流子定位：量子力学与固体力学之间的相互作用

自组织量子点中载流子的局域化是一个量子力学问题，需要解决的问题是电子和空穴的局域化势能由几何形状、化学成分和内置的机械应力-应变场决定。我们表明，掩埋金字塔量子点的纵横比的变化导致机械场分量的大量重新分布，这反过来为量子点的任何给定体积的最强载流子定位提供了某些重要条件。
