Abstract

The structural and optical characteristics of quaternary In0.52Ga0.18Al0.30As layers grown by molecular beam epitaxy were investigated using high resolution x-ray diffraction, absorption, photoluminescence and photoreflectance spectroscopy. The results showed that several transitions related to impurities and a free exciton feature were present, indicating that the exciton binding energy was smaller than predicted.
