Linear and nonlinear optical absorption coefficients and binding energy of a spherical quantum dot
Superlattices and Microstructures Cilt 47 ss. 556-566
Scopus Toplam 195 atıf DOI
The binding energy and wavefunctions of the 1s, 1p, 1d and 1f energy states of a spherical quantum dot (QD) with parabolic potential were calculated by using a method which is a combination of the quantum genetic algorithm (QGA) and the Hartree-Fock-Roothaan (HFR) approach. In addition, the linear and the third-order nonlinear optical absorption coefficients based on optical transitions in QDs with and without impurity were calculated. The results show that the parabolic potential has a great effect not only on the binding energies and but also on the optical absorption coefficients. Moreover, the calculated results also reveal that the linear and nonlinear optical absorption coefficients are strongly affected by the existence of impurity and the incident optical intensity. © 2009 Elsevier Ltd.

Off-center hydrogenic impurity in spherical quantum dot with parabolic potential
Superlattices and Microstructures Cilt 60 ss. 389-397

The binding energies of 1s-, 2p-, 3d- and 4f-states of a spherical quantum dot (QD) with parabolic potential are investigated by using the perturbation method. The binding energies are calculated as a function of impurity position. The results show that the dot radius and the parabolic potential have a great effect on the binding energies and there is a linear relationship between the dot radius and impurity shift corresponding to the binding energy maximum. In addition, the binding energies show a strong dependence on the impurity position within the dot. While the binding energies for s-state have the maxima for an on-center impurity case, the binding energy maxima of the p-, d- and f-states take place at different points between the center and edge of the dot. © 2013 Elsevier Ltd.
