Relaxation Dynamics of Free Carrierssituation. The free carriers are generated with some excess energy within the conduction and valence band, respectively. After excitation with an ultra-short pulse the carriers do not even have a thermalized distribution. The return of the semiconductor to an equilibrium state now occurs in several

Excitonic Complexesactually are prominent species in many semiconductors at intermediate excitation conditions in particular in structures of reduced dimensions. We start with the discussion of the particle properties of biexcitons, their non-linear optical spectroscopy and their recombination processes in bulk materi

Carrier Dynamics in Quantum Dotsntum dots wherever possible. The discussion starts with the capture of carriers into and their relaxation within the QD potential. We examine the phonon-bottleneck problem and continue with the role of Coulomb scattering. This review of ultra-fast relaxation at low densities closes with pointing out

Coherent Dynamics of Optical Excitationion. A prominent example is the optical Stark effect which leads to a blue (red) shift of a resonance (now between dressed states) for detuning of the exciting laser below (above) resonant conditions. We describe here this effect for various materials and their quantum-well structures and elaborate

Coherent Transportlation can arise which are coupled to an oscillation of a macroscopic polarization density. The latter can be made visible in ultra-fast optical experiments (probing oscillating inter-band polarization) or via the associated emission of THz radiation (due to an oscillating intra-band polarization).
