摘要
The molecular beam epitaxial growth of Si-doped GaAs, GaAs buffer layer, Al0.3Ga0.7As (x=0.3) and InxGa1-xAs (x=0.2-0.4) on GaAs(100) substrate were examined by x-ray diffraction. Crystallinity of each layer was compared for each sample. The x composition value calculated from the In flux for InGaAs layers were compared to value obtained from X-ray diffraction matching to the Vegard Law/Fournet model curves to obtain the lattice parameters.
