Understanding the polarization behavior in relaxor–ferroelectric crystals (IMAGE)
Caption
Lead-based B-site complex perovskites, also referred to as “relaxors,” exhibit large dielectric responses due to their complex structures. Understanding their atomic arrangements and inhomogeneous structures is, therefore, challenging. In this study, researchers from Japan used polarization-angle-resolved Raman spectroscopy on a compositionally graded crystal, identifying specific regions with enhanced charge accumulation. This information provides crucial insights into the material’s behavior and provides opportunities for improving the design and performance of ultrasound devices.
