Özet

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 D-2(+) 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.
