By a News Reporter-Staff News Editor at Journal of Technology -- Data detailed on Materials Science have been presented. According to news reporting originating in Chengdu, People's Republic of China, by VerticalNews journalists, research stated, "Highly epitaidal LaBaCo2O5.5+delta (LBCO) thin films were grown on different miscut (001) SrTiO3 substrates (miscut angle of 0.50 degrees, 3.0 degrees, and 5.0 degrees) to study the substrate surface step terrace effect on the in-plane electrical transport properties."
The news reporters obtained a quote from the research from the University of Electronic Science and Technology, "The microstructure studies by X-ray diffraction and transmission electron microscopy indicate that the as-grown films are A-site disordered cubic perovskite structures with the c-axis highly oriented along the film growth direction. The four-probe scanning tunneling microscopy (STM) studies show that the LBCO thin films grown on the vicinal SrTiO3 substrates have a typical semiconductor behavior with the substrate surface terrace step inducing anisotropic electronic transport properties."
According to the news reporters, the research concluded: "These results indicate that in highly epitaxial thin films the surface terrace step induced local strains can play an important role in controlling the electronic transport properties and the anisotropic nature."
