Natsuki TAKAHASHI won the Dean’s award for School of Engineering.

Natsuki TAKAHASHI won the Fellow Award of Atomic Energy Society of Japan for his research on optical memristors.

Our paper entitled “Dynamic Domain Motion Enhancing Electro-optic Performance in Ferroelectric Films” has been published in Appl. Phys. Lett. We found that rhombohedral (111)/(11-1)-PZT film, consisting of domains with two distinct out-of-plane polarization components, exhibited an enhanced EO response upon the application of an AC field of approximately 40 kV/cm. This enhanced EO response was directly related to field-induced reversible domain switching, as confirmed by electrical measurements and time-resolved synchrotron XRD. These results indicate that the dynamic domain motion in ferroelectrics is an effective strategy for enhancing the EO response.
