Abstract

Bi₂Ti₂O₇ (BTO) thin films have attracted attention because of its high dielectric constant and good insulating property. Bi₂Ti₂O₇ is an unstable phase in the process of the Bi₄Ti₃O₁₂ formation, and the phase structure can be stabilized by ionic modification. Bi₂Ti ₂O₇ and La-modified Bi₂Ti₂O ₇ thin films were prepared on Si (100) substrates by metalorganic decomposition (MOD). X-ray photoelectron spectroscopy (XPS) results indicated influence of oxygen vacancies and substituting Bi atoms with some La atoms. We investigated difference between Bi₄Ti₃O₁₂ and Bi₂Ti₂O₇ thin films. For (La_xBi _1-x)₂Ti₂O₇ thin films (BLT), phase stability is related to La modification.
