| Outline of Final Research Achievements |
This study has been devoted to develop the surface protonics materials, which originates from hydration acid-base reaction at surface of nano-grained oxides. It has been revealed that the formation and transport of protons are governed by the interaction between the surface-terminating protonic species and adsorptive species on them, which is strongly affected by surface modification with gasesous species. It has also been demonstrated that the thin films of insulating and dielectric oxides fabricated with a sputtering method show protonic conduction, which in some cases predominates the conduction behavior. And even if the protonic conduction is of minority, the proronic defects serve as the mediator of redox reaction of the oxide thin films, which significantly affects the electrical properties.
