“…Q2) What are the key structural factors that control and limit critical fields (E A and E B ), P max and P r ? Although the phase transition processes are complex, as reported in PbZrO 3 -based and NaNbO 3 -based systems [121][122][123][124], manipulative free dimensions about spatial, temporal and electric field offer a plethora of opportunities to unveil the unknowns. For example, in Pb(Zr 0.57 Sn 0.43 )O 3 -based ceramics, Fan et al observed local depolarization field-assisted AFE-to-FE transition during monotonic E loading using in situ (scanning) transmission electron microscopy (S/TEM).…”

Benefitting from exceptional energy storage performance, dielectric-based capacitors are playing increasingly important roles in advanced electronics and high-power electrical systems. Nevertheless, a series of unresolved structural puzzles represent obstacles to further improving the energy storage performance. Compared with ferroelectrics and linear dielectrics, antiferroelectric materials have unique advantages in unlocking these puzzles due to the inherent coupling of structural transitions with the energy storage process. In this review, we summarize the most recent studies about in-situ structural phase transitions in PbZrO3-based and NaNbO3-based systems. In the context of the ultrahigh energy storage density of SrTiO3-based capacitors, we highlight the necessity of extending the concept of antiferroelectric-to-ferroelectric (AFE-to-FE) transition to broader antiferrodistortive-to-ferrodistortive (AFD-to-FD) transition for materials that are simultaneously ferroelastic. Combining discussion of the factors driving ferroelectricity, electric-field-driven metal-to-insulator transition in a (La1−xSrx)MnO3 electrode is emphasized to determine the role of ionic migration in improving the storage performance. We believe that this review, aiming at depicting a clearer structure–property relationship, will be of benefit for researchers who wish to carry out cutting-edge structure and energy storage exploration.

“…As reported, the electric-field-induced FE phase displays a rhombohedral structure by in situ XRD. 43 Different from the temperature-related phase transition in BaTiO 3 , FE R is usually located in the temperature interval between AFE O and PE phases in the PbZrO 3 -based materials, which is also found in Figures 2f and 4b. 36,44,45 It indicates that the entropy of AFE O is lower than FE R in the AFE temperature range, as shown in Figure 4c.…”

Electrocaloric effect (ECE) in ferroelectric (FE)/antiferroelectric (AFE) materials offers a promising high-efficient and zero-emission solid-state cooling technology, whose materials design is usually focused on the morphotropic phase boundary (MPB) between two FE phases. This work constructs an MPB between an orthorhombic AFE and a rhombohedral FE phase in Pb 0.97−x Ba x La 0.02 Zr 0.95 Ti 0.05 O 3 (PBLZT100x, x = 0−0.08) ceramics and achieves a superior ECE performance. An unprecedented high electrocaloric strength of 1.52 K•mm/kV and an ultrahigh refrigeration efficiency (coefficient of performance = 16) are obtained in PBLZT4, in the MPB near AFE end. Moreover, a large negative ECE, with the highest strength up to −0.41 K•mm/kV, is also realized due to the electric field-induced AFE−FE transition. The coexistence of giant positive and negative ECEs at adjacent temperatures can further improve the cooling capacity (∼17%) of solidstate refrigeration in a well-designed cooling cycle. This work provides a brand new materials design strategy to achieve giant positive and negative ECEs simultaneously and a novel cooling cycle to efficiently utilize the two effects.

“…With increasing temperature, the AFE phase of PLZT is further stabilized and the energy storage performance is improved. [10][11][12][13][14][15][16][17][18][19][20][21][22] The energy storage density of PLZT increases with the zirconium content at the same temperature. Therefore, the energy storage behavior of PZT-based AFEs can be tuned by adjusting the Zr/Ti molar ratio.…”

Antiferroelectricity of NaNbO₃: Single‐crystal experimental study and first‐principles calculation

et al. 2022

Similar to the canonical antiferroelectric (AFE) compound PbZrO3 in Pb(Zr,Ti)O3 solid‐solutions, the presence of double hysteresis loops and that of electric field–induced phase transitions are important characteristics of NaNbO3 AFE materials; yet the phase transition behavior in the latter system is typically irreversible with the related mechanisms not fully understood. Here, we explore the phase transition mechanism of ferroelectric and AFE phases in NaNbO3 based on measurements of single crystals with different directions in conjunction with density‐functional theory (DFT) calculations. The tilting and distortion behaviors of the [NbO6] octahedra are explained by DFT, and the ion displacement in the lattice is traced. The tilting and distortion behaviors of the [NbO6] octahedra with different orientations are compared. We confirm that the tilt and distortion of the [NbO6] octahedra along the [1 1 1] direction is the main reason to improve the stability of AFE phase. This conclusion is verified by the experimental characterizations of large‐size NaNbO3 single crystals successfully obtained in this study.
