Abstract

In this article we theoretically study how the presence of charge carriers added to the conduction and valence band of a spherical CdTe quantum dot affects the optical properties, especially the absorption coefficient. For this study, we simulated the interband optical absorption spectrum for incident light with circular polarizations on the left (ê-), on the right (ê+) and linear (êz). We also consider Coulomb's interaction between optically excited and added carriers.
