Abstract

Exciton dynamics is experimentally studied for a heterostructure with a wide InGaAs/GaAs quantum well. The exciton-phonon, exciton-exciton, and excitons-carrier scattering is studied by means of reflectance spectroscopy in different experimental conditions. The non-radiative broadening of exciton resonances is extracted from the experimental data and used as a measure of the scattering efficiency. The exciton-phonon scattering is studied at different sample temperatures. The exciton-exciton and exciton-carrier scattering is studied at an additional illumination of the sample with radiation of a CW tunable laser with different photon energies. Direct information about the characteristic time of relaxation processes is obtained in the spectrally resolved pump-probe experiments.
