Abstract

The nature of defect differences between SrBi₂Ta₂O₉ (SBT) and Bi₄Ti₃O₁₂ (BTO) films is investigated using X-ray photoemission spectroscopy. The oxygen ions for SBT at the SrTa₂O₇ perovskite layers are much stable than those at the Bi₂O₂ layers. While oxygen vacancies on the BTO films could be induced both at the titanium-oxygen octahedra and at the Bi₂O₂ layers.
