Abstract

Investigations of the lattice dynamics of defects, such as oxygen vacancies, are important to understand the properties of PbTiO3 and related materials. Herein polarized Raman spectra of epitaxial PbTiO3 thin films with reduced and re-oxidized treatment were investigated. The oxygen-reduced spectrum displayed an additional mode related to oxygen vacancies, whereas the re-oxidized spectrum was the same as the initial one. The oxygen vacancy content increases as the intensity of additional mode increases, while the intensity of the B mode related to oxygen ions decreases. First-principles calculations of the phonon mode related to oxygen vacancies support the assignment of the additional mode.
