摘要：

We study intraband spectra, resulting from intraband transitions between the bound ground state of a semiconductor quantum dot and unbound continuum states in the host medium. The influence of excitonic coupling on these intraband absorption spectra and the formation of special excitons are discussed. Involving Coulomb coupled bound-to-continuum transitions, the spectra show the formation of bound excitons at the continuum edge and spectral shifts. The analyzed intraband absorption spectra exhibit different signatures for different initial carrier configurations.
