Abstract
- In this paper, the effect of quantum confinement on the energy band structure and the absorption coefficient of the spherical quantum dot has been investigated. The quantum dot chosen from the zinc blende materials such as ZnS, ZnSe and ZnTe. The approximation of the effective mass and the degenerate valence energy band at the center of the first Brillion region are considered in our calculations. Our theoretical calculations included dispersion relation of the bulk and the effect of quantum confinement on the energy band gap, joint density of states and absorption coefficient of quantum dot. We will display the curves of ZnS only, because the curves of other zinc blende materials are in the same behavior. All results show a good agreement between our theoretical calculations and experimental evidence from the literature. [ABSTRACT FROM AUTHOR]
