Time-resolved measurements and spatial photoluminescence distribution in InAs/AlGaAs quantum dots

Abstract We report the results of time-integrated and time-resolved photoluminescence spectroscopy on red-emitting self-organized InAs/Al0.6Ga0.4As quantum dots with indirect barriers. Spatially resolved PL measurements confirm that carriers excited in the Al0.6Ga0.4As barriers are consistent with a carrier hopping process between dots, a result also supported by time-resolved PL experiments.
