Abstract
Methods of two- and three-crystal X-ray diffraction and measurements of pho toluminescence (PL) spectra are used to study structural perfection and var iations in the PL spectra shape of GaAs epitaxial layers (ELs) grown by the molecular-beam epitaxy (MBE) technology on substrates with (100), (111)A, and (111)B orientation. A strong influence of arsenic-to-gallium molecular flow-rate ratio gamma on the structural property and shape of the PL spectr a of ELs is revealed. The optimum values of parameter gamma for each of the se substrate orientations are found.
