| 摘 要： | 用少体物理的方法研究处于外磁场中四层单电子垂直耦合量子点系统低激发态能谱随外磁场的变化关系。研究结果表明磁场的存在会导致基态出现不连续跃迁。量子点的耦合强度和电子之间的库仑相互作用对耦合量子点的基态跃迁有比较大的影响。

| Abstract: | This paper studied the energy levels of low-lying states of a vertically coupled four-layer single electron QDs system under a magnetic field by the using method of few-body physics. We find that dot-dot distance and electron-electron interaction strongly affect ground-state-transition of the coupled quantum dots. Because ground-state-transition exists in one-layer quantum dot, so we consider that the inter-dot correlation leads to the disappearance of ground-state-transition. |
