Abstract

We have demonstrated the capability and limitation of nondestructive photoluminescence and x-ray diffraction techniques in the characterization of GaAs, AlGaAs, InGaAs matched epitaxial layers grown by molecular beam epitaxy as well as quantum wells grown by metalorganic chemical vapor 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 Al_xGa_1-xAs layers in the range of x (0 less than or equal to x less than or equal to 1) and to solve some technological questions connected with layers lateral homogeneity.
