polar skyrmions in (PbTiO3)n/(SrTiO3)n superlattices suggests a perfect system for exploring interesting physical responses, including emergent toroidal order and local negative capacitance [1, 2]. Here, we explore the topologically non-trivial dipole textures of polar skyrmions, where local variations of ferroelectric polarization, chirality, electric field, and potential energy landscape are resolved using scanning electron nanodiffraction and a high-speed electron microscope pixel array detector (EMPAD) for collecting full CBED patterns [3].
