Abstract :
Oxygen vacancy in SrTiO3 is studied using the first principles calculation with the correction of onsite Coulomb interaction. In this paper, we performed the calculations on the multi oxygen vacancies in typical perovskite SrTiO3. We found that the oxygen vacancies tend to cluster in a linear way which makes the reduction of electron carrier concentration.
