Abstract

Raman spectroscopy is utilized to study the evaluation of vacancies in PbTiO₃ thin films subjected to hydrogen atmosphere heat treatment. The B₁ mode consisted of only oxygen ion vibration was shifted to lower frequency with increasing heat treatment temperature. It was considered that the oxygen ions were lacking from PbTiO₃, and that oxygen vacancies were generated. It was found that the frequency of the B₁ mode is proportional to oxygen ion content. Pb ions were also lacking in the PbTiO₃ thin films with oxygen ions and the number of oxygen vacancies was larger than that of Pb ions. We suggest that the Raman spectroscopy is a suitable tool for the evaluation of oxygen vacancies in PbTiO₃ thin films.
