Özet

In this study, we investigate the simultaneous effects of anisotropy and internuclear distance on the self-polarization of the D2+ complex in quantum dots for different confinement sizes. Numerical calculations were carried out within the effective mass approach using the two-dimensional diagonalization method. The obtained results reveal that a change in the internuclear distance and anisotropy parameter regulates the effective confinement potential of the system. The variation in effective confinement potential plays an important role in the spatial elongation of the wave function, which determines the observed behavior of the self-polarization effect (SPE). The magnitude of the SPE in the prolate case has been found to be greater than that of the oblate case. The obtained results reveal that the SPE of the D2+ complex can be arranged in quantum dots as desired by adjusting the internuclear distance and anisotropy of the system.
