TiO₂ is a material that still attracts the attention of researchers and has been intensively studied and applied as a photocatalyst and electron transport material. Gas phase methods are usually used to prepare anatase TiO₂ epitaxial thin films. We have previously reported its epitaxial growth on LaAlO₃ (001) by solvothermal method with fluoride ions, which is known as an effective surfactant for fabricating (001) faceted anatase TiO₂, and local structure analysis around the dopant of the fabricated thin film. For further local structure analysis, the substrate was changed to SrTiO₃ on which the thin film was fabricated by solvothermal method. The successful epitaxial growth of anatase TiO₂ on SrTiO₃ and the growth dependence on precursor compositions are presented.
