In archetypal ferroelectrics, the polarization and related properties result from structural lattice distortions.1 For example, in BaTiO3, it is the cationic off-centering versus the oxygen octahedra that is at the origin of the exceptional dielectric properties. Keeping these properties when downsizing such compounds is thus a challenge because the lattice elastic energy is disturbed by the surface energy even at relatively large grain size of several hundreds of nm...< Leer menos
