摘要

摘要本文用二维对角化方法得到了局限在量子点(QD)内的人工氢分子离子的电子结构、总能量和抗磁化率的各向异性和核间距离依赖的数值结果。我们通过调整量子点的大小、杂质原子之间的距离和量子点的各向异性，证明了配合物的抗磁化率和能级的可调性。结果表明，通过适当控制各向异性，可以实现系统电子态和抗磁化率的精确调谐。

Diamagnetic susceptibility of an artificial hydrogen molecule ion DD2 + confined to quantum dots: effects of anisotropy

ABSTRACT We present the numerical results obtained by the two-dimensional diagonalisation method concerning the anisotropy and internuclear distance dependence of the electronic structure, total energy and diamagnetic susceptibility of an artificial hydrogen molecule ion confined in the quantum dot (QD). We have demonstrated the existence of the tunability of the diamagnetic susceptibility and energy levels of the complex by adjusting the QD size, distance between the impurity atoms and the anisotropy of the QD. Consequently, results reveal that a precise tuning of the electronic states and diamagnetic susceptibility of the system can be achieved by proper control of the anisotropy.
