An Atomic-Scale Chemical Switch for Oxide Ferroelectricity

Abstract Interfacial chemistry offers new opportunities for designing ferroelectric materials, yet their coupling with intrinsic polarization remains largely unexplored. Here, we synthesize ferroelectric BiFeO3 nanoparticles with {100} facets covered by a Bi2FeO6-x Aurivillius-li...
