Abstract

The electrical properties of pure Anatase are investigated by impedance spectroscopy as function of temperature and oxygen partial pressure. The experimental results are fully interpreted by point defect chemistry. A transition from predominant Schottky to Frenkel cation disorder is observed when the temperature increases and/or the oxygen partial pressure decreases. The reduction enthalpies are near those obtained for Rutile in previous studies.
