Abstract

We present a theoretical analysis of Coulomb induced effects on intraband transitions between bound quantum dot and unbound continuum states of the host material. The intraband adsorption spectra show characteristic spectral signatures. In particular, the numerical results confirms the existence of bound excitons consisting of a localized carrier inside the quantum dot and a delocalized carrier of the continuum, which are spatially delocalized in the vicinity of the quantum dot.
