Abstract

The results of time-integrated and time-resolved photoluminescence (PL) spectroscopy on red-emitting self-organized InAs/Al_0.6Ga_0.4As quantum dots with indirect barriers were reported. The InAs-Al_0.6Ga_0.4As samples were grown by the Stranski-Krastanow technique using molecular beam epitaxy (MBE) on a [100]-oriented n⁺-GaAs substrate. It was confirmed by spatial resolved PL measurements that carriers excited in the Al_0.6Ga_0.4As barriers were consistent with a carrier hopping process between dots.
