New Horizons for Ferroelectrics

Since the discovery of ferroelectricity in 1920, dielectric research has provided a variety of fundamental physics problems and sustainable applications. Advances in synthesis and nanoscale characterization, along with theoretical innovations, have made ferroelectrics more versatile. In this perspective, we discuss several directions for future ferroelectric research in terms of flexoelectricity, ferroelectric topology, and lattice defects, as well as cooperation with associated fields.
