| Research Abstract |
Optical response and high resistivity of ferroelectric materials were discussed based on the materials design and materials synthesis. By the band width tuning for the ferroelectric materials through the elemental substitution, quite many materials were subjected to the measurements of the optical conductivity and photovoltaic effects. Based on the obtained data, strategies for the development of the optical catalysts and optical actuators were discussed.
