| Outline of Final Research Achievements |
There are strong interests on increased oxide ion conductivity at interface between different lattice parameter. In this study, increased oxide ion conductivity at interface between two mixed ion conductor were investigated. It was found that oxide ion conductivity of doped Pr2NiO4/CeO2 laminated nano thickness film was much increased by starin effects. In addition, oxygen dissociation activiity was also much increased on double colamunar film. Tensile stress caused by Au dispersion is also effective for increasing oxide ion conductivity in Pr2NiO4 based oxide. This study revealed that tensile strain shows large positive effects on oxide ion conductivity as well as surface activitiy.
