Observation of the spectral dependence of the spatial photocarrier redistribution in InAs/GaAs quantum dots

Abstract In this work we have studied the behavior of the spatial photocarrier distribution in InAs/GaAs self-assembled QDs as a function of the emission energy. Our results show that the spread of this distribution presents an energy dependence very similar to the observed spectral dependence of the photoluminescence (PL) decay time obtained by time resolved experiments.
