Abstract
We report on the growth and characterization of multiple quantum well structures by UHV/CVD epitaxy. X-ray diffraction is used to verify the expected layer periodicity and to determine the quantum well thickness. Photoluminescence measurements show peaks which we associate with recombination of excitons in the quantum wells. The measurements are consistent with high quality layers with small variation in quantum well thickness across a wafer.
