Tilt-driven ferrielectricity in PbZrO
Huazhang Zhang, Ying Liu, Carson Carroll +6
The paper demonstrates that adding an octahedral tilt to the antiferroelectric PbZrO₃ structure breaks symmetry and creates a ferrielectric polar phase, confirmed by first‑principl…
Silicon-compatible ideal antiferroelectricity with large digital electromechanical responses enabled by thermal-strain domain engineering
Hao Xiong, Huazhang Zhang, Liang Shu +16
Antiferroelectrics exhibit reversible antipolar-polar transformations, offering a compelling platform for multiple functionalities in modern nanoelectronics, yet deterministic cont…
Unlocking Static Polarization and Strain Density Waves in Perovskites by Softening a Hidden Antiferrodistortive Tilt Gradient Mode
Yajun Zhang, Devesh R. Kripalani, Xu He +9
Spin density waves (SDWs) represent a fundamental paradigm of spatially modulated order in condensed matter systems, yet their electrical and mechanical analogues polarization and…
First-order polarization process as an alternative to antiferroelectricity
Louis Bastogne, Lukas Korosec, Evgenios Stylianidis +6
Antiferroelectrics generate significant interest since their polarization versus electric field (PE) curves show typical double-hysteresis loops appealing for various applications.…
Finite-temperature properties and the hidden ferroelectric phase of bulk CaTiO from second principles
Huazhang Zhang, Michael Marcus Schmitt, Louis Bastogne +2
A second-principles effective interatomic potential is introduced for the prototypical perovskite CaTiO (CTO), relying on a Taylor polynomial expansion of the Born-Oppenheimer…
Mechanical coupling of polar topologies and oxygen octahedra rotations in PbTiO/SrTiO superlattices
Fernando Gómez-Ortiz, Louis Bastogne, Xu He +1
PbTiO/SrTiO artificial superlattices recently emerged as a prototypical platform for the emergence and study of polar topologies. While previous studies mainly focused on t…
