Abstract

Hetero-epitaxial BaTiO₃ layers were formed on the MgO(1 0 0) surface by thermal evaporation of titanium followed first by oxidation at 400 °C, subsequently by barium evaporation, and finally by annealing at 800 °C. The atomic structure of BaTiO₃ layers was investigated by the scattering intensity variation of He⁺ ions on time-of-flight impact-collision ion scattering spectroscopy and by patterns of reflection high energy electron diffraction. The result of our investigation reveals that cubic perovskite structured BaTiO₃ layers with the lattice parameter of bulk phase are grown on the MgO(1 0 0) surface.
