Outline of Final Research Achievements |
Ion and electron transport properties have been investigated from the viewpoint of atom or lattice scale by computational and experimental techniques. Oxygen vacancy formation energies in perovskite compounds are evaluated by first-principles DFT and thermogravimetry. The results indicate that electron and hole are localized at lattice even at elevated temperatures (>800 K). In addition, we suggest optimization method to design high ionic conduction materials by using genetic algorithm and kinetic Monte Carlo simulation. The trial research results indicate that optimizing arrangement of ion make the conductivity increase by a factor of 10.
