摘要：
Recent measurements of MOCVD-grown InAs/InGaAs quantum dots indicate a large homogeneous broadening at room temperature due to fast dephasing. The present work investigates the low-temperature homogeneous linewidth of individual photoluminescence lines from molecular beam epitaxy-grown In0.5Ga0.5As/GaAs quantum dots.
