... rate of InAs was deduced to be 0.013 ML/s and the QD formation was confirmed on GaAs (100) surface. After 15 s of growth interruption, a 20 nm GaAs capping layer was grown on top of the QDs layer ... buffer layer was grown at 600 °C followed by a reduction of the substrate temperature to 530 °C for the growth of 1.6 monolayer (ML) of InAs. By in situ reflection high-en...
