Periodic polar vortices in BaTiO3/SrTiO3 superlattices monolithically grown on silicon

Abstract Polar textures in ferroelectric superlattices have been so far reported almost exclusively in PbTiO 3 -based systems and predominantly on oxide substrates. Owing to their nanometer-scale dimensions and emergent functionalities, whirling topological polar textures would b...
