Theory of light scattering from semiconductor quantum dots: Excitation frequency dependent emission dynamics

We present a microscopic model for the dynamic scattering and emission spectrum of a semiconductor quantum dot, after coherent optical excitation. We investigate the spectral properties and the emission dynamics of the different scattering and emission contributions considering a V-type semiconductor quantum dot model under resonant conditions and include the coupling to LO-phonons via higher order Born approximations. This theory helps identifying the different contributions to the spectrum via time resolved calculations.

► Microscopic description of the emission dynamics from semiconductor quantum dots, involving the interaction with LO-phonons.
► Scattering and emission contributions evolve on different time scales.
► The dynamics strongly depends on the excitation frequency.
