Heteroepitaxial barium-doped NaTaO3 films on SrTiO3(001) substrate
Perovskite-structured NaTaO3 films were epitaxially deposited on centimeter-sized SrTiO3(001) wafers by hydrothermal and solvothermal reactions to examine the surface science for an efficient photocatalytic watersplitting reaction. The addition of Ba cations in the starting solutions afforded Ba-doped NaTaO3 films. X-ray fluorescence holography was employed to investigate and confirm the heteroepitaxial relationship between the Ba-doped film and substrate.
