Abstract

We report a study of interfacial quality of strained-layer InGaAs/GaAs quantum well lasers grown by gas-source molecular beam epitaxy. It was found that the growth temperature (Tgr) of the InGaAs layer plays an important role in the interfacial quality. For Tgr < 515 °C, a large amount of non-radiative recombination centers is likely to exist in the InGaAs/GaAs quantum well, which can be attributed to the presence of vacancies and atom clusters and lattice misfit defects. For Tgr > 515 °C, the InGaAs/GaAs interfaces show significant roughness due to In segregation. Rapid thermal annealing grades the InGaAs/GaAs interface because of interdiffusion of group-III atoms at the interface, and removes most of the non-radiative recombination centers from the low Tgr (<515 °C) samples. In addition, we observed that the interfacial quality of the InGaAs/GaAs quantum well shows no strong dependence on (100) vicinal orientations of GaAs substrate.
