| Research Abstract |
The evaluation technique that provides a broadband conductivity spectra from low to THz frequencies for oxygen ion conductor ceramics was developed in this study. The relationship between the optical phonon behavior and the ion conductivity was quantitatively investigated by applying this technique to some oxygen ion conductors(ex. yttria-stabilized zirconia). As a result, the existence of the relation between these parameters; smaller damping factor of the optical vibration leads to higher ion conductivity, was found.
