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 twodimensional
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.
