“…In PLZT, MacLaren discovered that the dipoles are not equal in magnitude but form a sinusoid (Figure 29). 218 Chen confirmed the sinusoidal dipole wave in PNZST, but also observed that the atomic displacements have components along two orthogonal <110> directions 219 . More strikingly, they showed that polarization may not be fully compensated in INC AFE.…”

Antiferroelectric (AFE) materials are of great interest owing to their scientific richness and their utility in high-energy density capacitors. Here, the history of AFEs is reviewed, and the characteristics of antiferroelectricity and the phase transition of an AFE material are described. AFEs are energetically close to ferroelectric (FE) phases, and thus both the electric field strength and applied stress (pressure) influence the nature of the transition. With the comparable energetics between the AFE and FE phases, there can be a competition and frustration of these phases, and either incommensurate and/or a glassy (relaxor) structures may be observed. The phase transition in AFEs can also be influenced by the crystal/grain size, particularly at nanometric dimensions, and may be tuned through the formation of solid solutions. There have been extensive studies on the perovskite family of AFE materials, but many other crystal structures host AFE behavior, such as CuBiP 2 Se 6 . AFE applications include DC-link capacitors for power electronics, defibrillator capacitors, pulse power devices, and electromechanical actuators. The paper concludes with a perspective on the future needs and opportunities with respect to discovery, science, and applications of AFE.

“…Moreover, due to the field-induced reversible transformation between ferroelectric and anti-ferroelectric phases, the anti-ferroelectric materials exhibit double characteristic hysteresis loop in their P-E curves. [107][108][109] For the tetragonal I4cm MAPbI 3 perovskite, as shown in Figure 3C, the C-N dipole shows an H-T alignment along the [001] direction and is consistently ordered. The consistently ordered MA + dipoles lead to the breaking of the centrosymmetry of the unit cells with spontaneous polarization, [59][60][61]69 whose value can be 4-8 μC/cm 2 for MAPbI 3 .…”

Methylammonium lead triiodide (MAPbI 3 ) perovskite has attracted broad interest for solar cells, light-emitting diodes, and so forth. Experiments have captured that the alternative coexistence of polar and nonpolar domains in MAPbI 3 can be switched by photons and phonons. Therefore, it is urgent to clarify the interplay among the crystal space group, polarity, ferroic properties, and switching mechanisms for MAPbI 3 . Herein, we perform a statistical synthesis on ferroelectric and anti-ferroelectric features for tetragonal MAPbI 3 perovskite. The polar and nonpolar domains are ferroelectric with the I4cm space group and anti-ferroelectric with the I4/mcm space group, respectively.The domain wall (DW) separating nonpolar and polar regions is charged. Combining the effects of the electric properties of ferroic domains and the charged DWs, novel switching mechanisms are proposed in which photons and phonons drive alternations between ferroelectric and anti-ferroelectric domains, which provide a reasonable approach to clarify the ambiguous understanding of ferroic behavior for MAPbI 3 perovskite.

Since the discovery of Rochelle salt a century ago, ferroelectric materials have been investigated extensively due to their robust responses to electric, mechanical, thermal, magnetic, and optical fields. These features give rise to a series of ferroelectric‐based modern device applications such as piezoelectric transducers, memories, infrared detectors, nonlinear optical devices, etc. On the way to broaden the material systems, for example, from three to two dimensions, new phenomena of topological polarity, improper ferroelectricity, magnetoelectric effects, and domain wall nanoelectronics bear the hope for next‐generation electronic devices. In the meantime, ferroelectric research has been aggressively extended to more diverse applications such as solar cells, water splitting, and CO2 reduction. In this review, the most recent research progress on newly emerging ferroelectric states and phenomena in insulators, ionic conductors, and metals are summarized, which have been used for energy storage, energy harvesting, and electrochemical energy conversion. Along with the intricate coupling between polarization, coordination, defect, and spin state, the exploration of transient ferroelectric behavior, ionic migration, polarization switching dynamics, and topological ferroelectricity, sets up the physical foundation ferroelectric energy research. Accordingly, the progress in understanding of ferroelectric physics is expected to provide insightful guidance on the design of advanced energy materials.
