Summary: In this study, the piezoelectric properties of 0.7BFBT-T were enhanced through quenching. A suitable quenching temperature increased the content of the rhombohedral phase, leading to a highly distorted structure and magnification of the dipole moment, which was beneficial for enhancement of the polarity. Furthermore, quenching inhibited oxygen vacancies and increased the size and orderliness of domains, reducing the pinning effect.

Summary: Hard piezoelectric properties were investigated in lead-free BiFeO3-BaTiO3 (BF- BT) ceramics. Rhombohedral (R) phase ceramics of (1 - x)BF-xBT (x = 0.20-0.30) were prepared. The x = 0.20 ceramic showed the best hard piezoelectric properties, with the highest Q(m) = 403 and the highest T-C = 607°C. In contrast, the x = 0.30 ceramic showed soft piezoelectric properties, with d(3)(3) = 301 pC/N and k(p) = 0.33, and T-C = 510°C. The BF-BT system in the R-phase-rich region has good hard piezoelectric properties for transducer applications.

Summary: In this paper, an effective strategy to overcome the trade-off between piezoelectric coefficient and the Curie temperature is proposed by co-doping K+ and Nb5+ ions at A/B sites, achieving a combination of high TC and d33 in BiFeO3-BaTiO3-based ceramics. The MPB region is confirmed in a narrow range of x = 0.0075-0.01 by the Rietveld refinement of XRD patterns and Raman spectroscopy deconvolution. An optimized composition with 1 mol% K/Nb co-dopants possesses a high Curie temperature (TC = 604 degrees C) along with d33 = 163 pC/N, kp = 43 %, Pr = 57.94 mu C/cm2, and Ps = 68.18 mu C/cm2. An outstanding thermal stability to 540 degrees C is verified via the temperature dependence of d33 and in situ Raman spectroscopy. This work not only provides a potential lead-free candidate material for high-temperature piezoelectric applications, but also offers a feasible strategy to design high-temperature dielectrics by exploiting site engineering.

Summary: BiGaO3 doped BiFeO3-BaTiO3 ceramics were synthesized and their phase analysis, microstructure, piezoelectric, ferroelectric, dielectric properties, and thermal stability were investigated. The ceramics showed rhombohedral (R) and tetragonal (T) structures, with particle dimensions increasing with the concentration of BiGaO3. Electrical properties were improved with the addition of a small amount of BiGaO3, with increased piezoelectric constants, electromechanical coupling coefficient, mechanical Quality Factor, decreased dielectric loss, increased residual polarization intensity, and specific Curie temperature and depolarization temperature. The piezoelectric response of the ceramics increased rapidly with increasing temperature, reaching a maximum at 340 ℃ and gradually reducing to zero at 450 ℃.

Summary: BF-ST ceramics are a novel class of lead-free dielectric materials with notable dielectric constants and remarkable thermal stability. The microstructure and electrical properties of BF-ST ceramics near the morphotropic phase boundary were comprehensively investigated. The findings show that increasing the SrTiO3 content leads to changes in phase fractions and the formation of a distinctive heterogeneous core-shell microstructure.

Summary: Introducing BNSTNZ into BF35BT ceramics resulted in a shift from normal-ferroelectric to relaxor-ferroelectric phase, leading to high dynamic piezoelectric coefficient and relatively high static piezoelectric coefficient at the optimum composition. This composition shows great potential for high-temperature piezoelectric applications due to its enhanced field-induced strain response.

Summary: In this study, in-situ synchrotron x-ray diffraction and transmission electron microscopy were conducted to investigate the structural mechanism of BF-PT-0.19Ba(Zr,Ti)O3 high-temperature piezoceramic. It was found that an irreversible transition from tetragonal phase (T phase) to rhombohedral phase (R phase) occurred after poling, leading to significantly enhanced irreversible domain switching of both R and T phases. This study provides a new mechanism for designing high-performance high-temperature piezoelectric ceramics.

Summary: The lead-free Sm-modified 0.67Bi(1.03)FeO(3)-0.33BaTiO3 ceramics system was systematically studied, and a phase diagram was developed based on crystal structure and electromechanical properties. By modifying Bi3+ sites with Sm3+, the long-range ferroelectric order of the rhombohedral and tetragonal mixed phase was changed to a short-range relaxor ferroelectric order. Excellent static and dynamic piezoelectric coefficients were achieved near the morphotropic phase boundary, and the piezoelectric strain performance was enhanced at the crossover boundary of the normal and relaxor ferroelectric phases.

Summary: The origins of unipolar strain, strain hysteresis, and remnant strain in Mn-modified BF-BT ceramics near the pseudo-cubic and rhombohedral (PC-R) phase boundary were investigated using high-energy synchrotron X-ray diffraction. It was found that the largest unipolar strain occurred at the composition with a single pseudo-cubic phase, due to the synergetic contributions from reversible phase transition, non-180 degrees domain switching, and lattice distortion. The phase boundary composition exhibited irreversible phase transition, with the unipolar strain attributed to lattice distortion. The lowest strain hysteresis and remnant strain were observed in BF-BT ceramics with rhombohedral phase, as reversible lattice distortion dominated the strain level.

Summary: By studying three different series of lead-free ceramics, two morphotropic phase boundaries (MPBs) were discovered, revealing the relationship between piezoelectric performance and crystal structure. The significant enhancement in piezoelectric strain response due to local structural heterogeneity caused by La3+ doping serves as the basis for the improvement in ceramic performance.

Summary: This study breaks the crystallographic symmetry and induces large and sustainable piezoelectric effects in centrosymmetric materials. The experiment shows the generation of extraordinarily large piezoelectric responses in cubic fluorite gadolinium-doped CeO2-x films, which are two orders of magnitude larger than the responses observed in the presently best-known lead-based piezoelectric relaxor-ferroelectric oxide. This finding provides opportunities to design environmentally friendly piezoelectric materials.

Summary: The method of generating x-rays using the pyroelectric effect is suitable for portable and low-power real-time in-field and on-line analysis applications, but the x-ray intensity produced is low and inconsistent compared to conventional x-ray tubes. The ratio of the pyroelectric coefficient to relative permittivity determines the performance of the x-ray generator.

Summary: Domain walls, as dynamic interfaces in piezoelectric materials, have a significant impact on the functionality under applied external fields. Conductive domain walls in polycrystalline BiFeO3 have been found to result in frequency-dependent dispersion of lattice strain and ferroelastic domain wall motion. An anomalous field-dependent behavior of ferroelastic domain wall motion and lattice strain during field cycling is revealed, which is interpreted as the generation of opposing fields accompanying domain wall motion.

Summary: Electrostriction is a property of dielectric materials where a mechanical deformation is induced in response to an applied electric field. This study reports an engineered electrostriction effect achieved through the controlled interfaces of Gd2O3-doped CeO2 and Er2O3-stabilized delta-Bi2O3 on NdGaO3 substrates. The electrostriction coefficient achieved exceeds the best known materials by three orders of magnitude, and is attributed to the coherent strain from interfacial lattice discontinuity.

Summary: The atomic-level response of zigzag ferroelectric domain walls was investigated using in situ bias scanning transmission electron microscopy. The position of the domain wall did not follow the strain field when the electric field was applied, which can be explained by low mobility defect segregation at the initial position of the domain wall. The triangular apex of the zigzag wall was pinned but changed its shape and became asymmetric under electrical stimuli.

Summary: We present a novel approach of intrinsic strain engineering in tetragonal ferroelectric single-crystal BaTiO3 by irreversible high-temperature plastic deformation, similar to thin film techniques. Introduction of well-aligned dislocations along the [001] axis and associated strain fields in the [110]/[1 over bar 10] plane leads to the nucleation of only in-plane domain variants. Combining experimental observations and theoretical analyses, we demonstrate that mitigating domain instability and extrinsic degradation processes during aging and fatigue requires careful tuning of the ratio between in-plane and out-of-plane domain variants.
