Translational antiphase boundaries in NaNbO\u2083 antiferroelectrics
, 2023 : Planar defects are known to be of importance in affecting the functional properties of materials. Translational antiphase boundaries (APBs) in particular have attracted considerable attention in perovskite oxides, but little is known in lead-free ...

Nanostructures formation in ferroelectrics in the process of phase transformation [PDF]
Journal of Advanced Dielectrics, 2014 Inhomogeneous states caused by the coexistence of the ferroelectric (FE) and antiferroelectric (AFE) phases in lead–zirconate–titanate based solid solutions have been investigated. It has been found that the domains of the FE and AFE phases with sizes of

Atomic Imaging of Electrically Switchable Striped Domains in β′‐In2Se3
Advanced Science, 2021 2D ferroelectricity in van‐der‐Waals‐stacked materials such as indium selenide (In2Se3) has attracted interests because the ferroelectricity is robust even in ultrathin layers, which is useful for the miniaturization of ferroelectric field effect ...

Orthorhombic ABC Semiconductors as Antiferroelectrics
Physical review letters, 2012 We use a first-principles rational-design approach to identify a previously unrecognized class of antiferroelectric materials in the 𝑃𝑛𝑚𝑎 MgSrSi structure type. The MgSrSi structure type can be described in terms of antipolar distortions of the nonpolar 𝑃6₃/𝑚𝑚𝑐 ZrBeSi structure type, and we find many members of this structure type are close in ...

Flexoelectricity in antiferroelectrics
, 2021 Flexoelectricity (coupling between polarization and strain gradients) is a property of all dielectric materials that has been theoretically known for decades, but only relatively recently it has begun to attract experimental attention.

Physical Review LettersAntiferroelectricity (AFE) is a fundamental concept in physics and materials science. Conventional AFEs have the picture of alternating local electric dipoles defined in real space. Here, we discover a new class of AFEs, termed type-II AFEs, which possess opposite polarizations defined in momentum space across a pair of symmetry decoupled subspaces ...
