We systematically analyzed the Al composition dependences of structural properties (AlxGa1−x)2O3 thin films grown on β-Ga2O3 (010) substrates. The crystal structure was characterized by x-ray diffraction, and surface morphology observed reflection high-energy electron diffraction atomic force microscopy. In 100-nm-thick films, crystallinity began to degrade defects appeared when x exceeded abou...
