Abstract

Time resolved photoluminescence (PL) on InGaAs/GaAs showed that the carrier dynamics is affected by two distinct factors: the capture of the photo-excited carriers into the quantum dot (QD) states and the carrier relaxation inside the dots. The ratio of these two components is a function of the excitation intensity. We also demonstrate the influence of the Auger-like scattering in the carrier relaxation process in InGaAs/GaAs quantum dots by analysing the intensity dependence of time resolved spectra.
