Abstract
Accurate theoretical description of optical phenomena in semiconductor quantum dots (QDs) depends on the description accuracy of the energy structure of the QD. For the energy structure description the existent methods, such as, the tight-binding method, the effective bond-orbital model, the first-principles calculations or the multi-band approach within p k theory, have some limitations either in the accuracy of the predicted electronic structures or the computation efficiency. In this context, the phonon influence on the optical properties makes the theoretical description of the optical phenomena in QDs more complex. In this chapter, we introduce several methods and techniques to describe the phonon influence on the emission and absorption spectra of semiconductor QDs. They are implemented on simplified models of QDs that can capture the main physics of the studied phenomena.
