Several approaches to the atomistic simulation of oxides have been used over the last fifty years, ranging from simple ionic models (Born), electron-gas models (Gordon-Kim), shell models (Overhauser), Charge transfer models (Streitz-Mintmire), multibody interactions (WIlson-Madden, Scandalo-Tangney), tight-binding and others. I will review the relationship between these approaches and some of their successes and failures compared to first-principles calculations, with particular reference to my own group's experience with ZrO2, Al2O3 and SrTiO3 and defect chemistry.
