| Outline of Final Research Achievements |
Conducted in the present study is the development of new functionality which can control dielectric properties by photoirradiation. We have discovered the instantaneous photo-dielectric effect in La(Al0.99Zn0.01)O3, the 1% of Al-sites in LaAlO3 are substituted by Zn ions, where the dielectric permittivity increases under the photoirradiation and immediately recovers to the initial value when the photoirradiation ceases. The persistent photo-dielectric effect has furthermore been found in Ba(Al0.97Zn0.03)2O4, in which the increase of permittivity remains after switching the photo-irradiation off. The results of the present study open a new realm of light-matter interactions and form the foundation for the development of innovative photo-electric devices.
