| Popis: | The present study seeks to scrutinize the optical properties of a double ellipsoidal quantum dot (EQD) containing two electrons. The effect of the electron–electron interaction on the absorption coefficients for different values of the ellipticity constant is investigated. The perturbation method is used and for different values of the ellipticity constant, the absorption coefficients, group velocity and group index are calculated as a function of the incident photon energy. The results show that the absorption coefficients of the double EQD increase with increases in the ellipticity constant and shift to higher energy as β decreases. |
