Abstract
We report photoluminescence data from three InAs/AlAs quantum dot samples with different densities and separations, respectively. For medium density the quantum dot related emission peak shows a blueshift with increasing excitation power whereas for very high dot density a redshift is observed. These opposite peak shifts are explained by different carrier transfer processes amongst lateral coupled QDs.
