Domain-wall-to-domain interconversion in a polar conducting oxide
Martin F. Sarott, Majid Ahmadi, Johanna van Gent González +13
Domain walls in ferroic crystals are topological defects with a symmetry distinct from the domain interior, allowing them to display functionalities that are otherwise forbidden in…
Polar discontinuity screening by charge disproportionation in ferroelectric-nickelate superlattices
Edith Simmen, Jonathan Amara, Philippe Ghosez +1
We use density functional theory (DFT) to demonstrate rearrangement of charge disproportionation as a new mechanism for screening polar discontinuities at heterointerfaces. We focu…
Tilt-driven ferrielectricity in PbZrO
Huazhang Zhang, Ying Liu, Carson Carroll +6
We reveal a tilt-driven mechanism for ferrielectricity in prototypical antiferroelectric PbZrO. Specifically, introducing an additional octahedral tilt into the antiferroelectr…
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.…
