“…One of the important factors in both the electronic and optical properties of MSQDs is the number of wells in the structure. When the literature is examined, it is seen that the effect of the number of wells in multiple quantum wells have been widely investigated [25][26][27][28][29][30][31]. However, there are very few reports on MSQD [32][33][34].…”

In the current study, the probability densities and binding energy of the ground state and first excited sate in multishell quantum dot with parabolic confinement potential have been examined. Also, the effects of core radius, the number of well in structure and the presence of impurity on the total optical absorption coefficient have been investigated. The finite difference method has been used to obtain the energy levels and related wave functions of the system within framework effective mass approximation. The results obtained reveal that the number of well, especially the first five values, have a considerable impact on the critical core values of binding energy. It is found that the presence of impurity and the number of wells cause a blue shift in the peak positions of total absorption coefficients. Moreover, our results show that these factors have an important effect on the magnitude of optical properties.
