The substitution of hydride anions (H−) into transition metal oxides has recently become possible through topotactic reactions or high-pressure synthesis methods. However, the fabrication of oxyhydrides is still difficult because of their inherentl

Ionic conduction in LaOF was investigated by density functional theory-based first-principles calculations. The origin and microscopic mechanism of selective fluoride ion conduction in LaOF were investigated by evaluating the formation energy of the

In this study, we investigated oxide ion conduction in N-/F-doped ZrO2 systems under tensile epitaxial strain by ab initio molecular dynamics (MD) simulations. In our previous study, we discussed the effects of lattice strain, oxygen vacancies, and c

Mixed-anion perovskites such as oxynitrides, oxyfluorides, and oxyhydrides have flexibility in their anion arrangements, which potentially enables functional material design based on coordination chemistry. However, difficulty in the control of the a

It has been recently reported that H-doping of SrFeO2 induces an insulator-to-metal transition but generates only a small amount of carrier electrons. To investigate the crystal structure of H-doped SrFeO2 (SFOH) and the origin of its peculiar transp

The crack propagation in a positive electrode of lithium (Li)-ion batteries degrades the performance of Li-ion batteries. The crack propagation is driven by the Li intercalation- and deintercalation-induced stress-field in the electrode. In order to

The oxygen ionic conduction in ZrO2 systems under tensile epitaxial strain was investigated by performing ab initio molecular dynamics (MD) calculations based on density functional theory (DFT) to elucidate the essential factors in the colossal ionic

The Nb-doped anatase TiO2 is considered one of the most promising alternative transparent conducting oxides to substitute for indium tin oxide. However, studies have found that the conductivity emerges only in the anatase form, not in the rutile form

Interstitial oxygen atoms (Oi) in TiO2 were investigated using the density functional theory-based first-principle band structure method. Two polymorphs of TiO2, anatase and rutile structures, were considered. A symmetric O−O structure was obtained
