In this study, the simultaneous effects of anisotropy and internuclear distance on the self-polarization of the D+2 complex in quantum dots were investigated. Numerical calculations using the two-dimensional diagonalization method revealed that changes in internuclear distance and anisotropy parameter can regulate the effective confinement potential of the system. The variation in effective confinement potential plays a crucial role in the spatial elongation of the wave function and determines the observed behavior of the self-polarization effect.
In this study, we investigate the simultaneous effects of anisotropy and internuclear distance on the selfpolarization of the D+2 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 D+ 2 complex can be arranged in quantum dots as desired by adjusting the internuclear distance and anisotropy of the system.
