| Research Abstract |
A wide variety of material properties of oxides are strongly dependent on their nonstoichiometric characters. In the present study, first-principles thermodynamics methods have been developed for finding and understanding structure-property relationships of materials. Appling the methods to binary metal oxides and perovskite multicomponent oxides, new ordered phases and new defects originated from their nonstoichiometric properties have been discovered.
