Abstract

In article number 1901373, J Wu, B Yang, D Zhang, H Yan and co-workers demonstrate the importance of terahertz (THz) technology in decoding the intrinsic structural dynamics of Bi0.5Na0.5TiO3-based ferroelectrics. During DC-field poling cycles, the variated dielectric response probed by reflected-THz beam is coordinated to the permanent change of polar clusters. The evolution of perovskite unit cells symbolizes the irreversible field-induced structural changes at the lattice scale.
