ABSTRACTThe carrier-phonon interaction in self-organized In(Ga)As/GaAs quantum dots is investigated under resonant excitation of the ground-state transition. Different phonon-coupled processes are observed. The distinction between Raman scattering and hot-luminescence process has been resolved by time-dependent photoluminescence measurements. The quantum dot LO (33.8 meV) as well as an interface (36.5 meV) phonon mode is observed by resonant Raman scattering. For the QD LO phonon mode, a very short radiative lifetime of 10 ps was found.

Anomalous strong linear anisotropy of resonant Raman scattering in open ZnCdSe / ZnSe nanowires has been found. The anisotropy value is more than twice as that due to the anisotropy of exciton–photon interaction which is the characteristic for open nanowires. It is suggested that the anomalous anisotropy is connected with different probability of Frohlich exciton–LO phonon interaction at scattering via transverse and longitudinal exciton states.
