Abstract
We have demonstrated the capability and limitation of nondestructive photoluminescence and X-ray diffraction tecniques in the characterization of GaAs, AlGaAs, InGaAs matched epitaxial layers grown by molecular beam epitaxy as well as quantum wells grown by metalorganic chemical vapour deposition. The application of the X-ray diffraction and the photoluminescence methods to the same objects made it possible to control Al content in the AlxGa1-xAs layers in the range of x (0≤x≤l) and to solve some technological questions connected with layers lateral homogeneity.
