Abstract: Ferroelectric-dielectric superlattices consisting of alternating layers of ferroelectric PbTiO_{3} and dielectric SrTiO_{3} exhibit a disordered striped nanodomain pattern, with characteristic length scales of 6 nm for the domain periodicity and 30 nm for the in-plane coherence of… read more here.

DOI: 10.1103/physrevlett.119.207604
Abstract: We reveal that concurrent events of inherent entropy boosting and increased synchronization between A- and B-site cation vibrations of an ABO_{3}-type perovskite structure give rise to a larger piezoelectric response in a ferroelectric system at… read more here.

DOI: 10.1103/physrevlett.121.137602
Abstract: Although discussions of structural phase transitions in prototypical ferroelectric systems with the perovskite structure, such as BaTiO_{3} and PbTiO_{3}, started almost seventy years ago, an atomic-level description of the polar characteristics as a function of… read more here.
