DOI: 10.1142/s2010135x19300020
Abstract: Relaxor ferroelectrics have been extensively studied due to their outstanding dielectric, piezoelectric, energy storage, and electro-optical properties. Although various theories were proposed to elaborate on the relaxation phenomena, polar nanoregions formed by disruption of the… read more here.
