Abstract: PbTiO3-SrTiO3 (PTO-STO) superlattice has been shown to host a variety of polarization domain structures depending on the periodicity of the superlattice. High periodicity superlattices favor a1/a2 domains, while low periodicity superlattices host flux closure domains… read more here.

Abstract: Nontrivial topological structures offer a rich playground in condensed matters and promise alternative device configurations for post-Moore electronics. While recently a number of polar topologies have been discovered in confined ferroelectric PbTiO3 within artificially engineered… read more here.

DOI: 10.1063/5.0146713
Abstract: In ferroelectric heterostructures, the interaction between intrinsic polarization and the electric field generates a rich set of localized electrical properties. The local electric field is determined by several connected factors, including the charge distribution of… read more here.
