【摘要】 用精确对角化的方法研究了处于外磁场中三层单电子垂直耦合量子点系统基态能谱。研究发现外磁场的存在会导致基态角动量出现不连续跃迁,量子点间的距离对耦合量子点的基态能谱有很大的影响,量子点内部的关联会导致一系列基态跃迁的消失。更多还原

【Abstract】 The energy levels of a vertically coupled three-layer single electron QDs system under a magnetic field by the exact diagonalization of the Hamitonian matix is studied.This study shows that discontinuous groundstate energy transitions induced by an external magnetic field,the dot-dot distance strongly affect the energy levels of coupled quantum dots and the inter-dot correlation leads to the disappearance of ground-state-transition.更多还原
