Abstract

In-rich quantum-dot-like structures in In0.19Ga0.81N multiquantum well (MQWs) were investigated by means of high-resolution transmission electron microscopy (HRTEM) and energy-filtered (EF) TEM. It was found that thermal annealing at 900 °C led to a quasi-regular quantum-dot-like structure. However, such a structure was destroyed when the annealing temperature was raised to 950 °C. Temperature-dependent photoluminescence (PL) measurements showed quite consistent results. A blue shift of the PL peak position and narrowing of the PL spectral width after thermal annealing were observed.
