Summary: Lead zirconate titanate (PZT)-based piezoelectric ceramics with increasing average grain size were prepared and their properties were systematically investigated. The results showed that the electromechanical properties of the ceramics improved significantly with increasing grain size. In addition, the formation of non-180 degrees domain walls was suppressed in the fine-grain samples, while enhanced domain wall mobility was observed in the coarse-grain samples. This study confirmed that grain size engineering is an effective strategy for designing piezoelectric materials with excellent combination properties.

Summary: In this study, we experimentally investigated the photo-induced direct current (DC) drift in a lead lanthanum zirconate titanate (PLZT) Mach-Zehnder modulator with large optical input power. We clarified the mechanism behind the short-term and long-term DC drift and discussed each case. Our findings suggest that the short-term DC drift can be reduced by adjusting the buffer-layer resistivity of the PLZT modulator, while the impurity level of the buffer layer affects the long-term DC drift.

Summary: This work investigates the laser-based annealing process of sol-gel-derived PZT53/47 thin films and demonstrates that the crystallization time of chemical solution deposited PZT thin films can be significantly reduced by using laser radiation. The study also reveals that short interaction times during laser annealing shift the nucleation of the PZT thin films from epitaxial to heterogeneous nucleation.

Summary: A method for accurately measuring the switching time between antiferroelectric and ferroelectric phases was designed using electrically induced light scattering effects. It was found that in lanthanum-modified lead zirconate titanate transparent ceramics, the switching times decreased with higher applied electric fields, with the logarithm of the switching time being proportional to the reciprocal of the electric field. The random orientation of polycrystalline structures with dispersed mixed phases was identified as the intrinsic mechanism affecting the switching times. Additionally, smaller electrode sizes resulted in faster switching speeds in the same electric field due to a size effect caused by higher dielectric constants and longer rising times of the applied electric field.

Summary: AC-poling of PIN-PMN-PT single crystals with a thickness of 0.06-0.16 mm was studied. Enhancements in piezoelectric and dielectric properties were observed when the thickness exceeded 0.1 mm. However, inconsistent poling effects were found in crystals with thickness below 0.1 mm. Surface roughness was measured to correlate with poling effects, and temperature-dependent dielectric permittivity spectra were measured to explore the thermal stability of ferroelectric phases.

Summary: Efficient two-photons and three-photons pumped upconversion emission were investigated in highly transparent Er3+ ions doped lead lanthanum zirconate titanate ceramics excited by near infrared lasers. Temperature dependent spectral changes of the multi-photons upconversion emission were explored, and highly sensitive temperature sensors were obtained based on the energy difference between 2H11/2 and 4S3/2. This work is useful for developing a highly sensitive non-contact temperature measurement sensors, providing the necessary theoretical basis for practical application.

Summary: In this paper, the effects of Zr/Sn ratio on the phase structure and dielectric properties of (Pb0.98La0.02)(ZrxSn1-x)(0.995)O-3 antiferroelectric materials were systematically studied. The results showed that the saturation polarization strength and energy storage density increased with increasing Zr content, reaching peak values at certain Zr/Sn ratios before decreasing. A new intermediate state called multicell cubic appeared during the phase transition, different from traditional antiferroelectric materials. Additionally, the Curie temperature of the materials increased with increasing Zr content before decreasing. Based on these results, PLZS AFEs could be a promising high-power energy storage material.

Summary: The d(33,eff) value of BCZT thin film prepared by RF magnetron sputtering was measured to be approximately 70 p.m. V-1, which is comparable to other lead-free thin film compositions. XPS analysis revealed the influence of mixed-valence Ti states and oxygen chemical ions on the d(33,eff) value. The perovskite structure and good piezo-response of the TF make it a promising storage device for the electronic industry.

Summary: In this paper, a cooperative optimization strategy is proposed to achieve outstanding energy-storage performance in NBST-based ceramics. Substituting NN for NBST generates an ergodic state and induces polar nanoregions. Applying VPP to the ceramics further increases compactness and breakdown strength. The optimized ceramics possess improved energy-storage characteristics and temperature adaptability.

Summary: The ordering of isolated circular ferroelectric nanodomains was observed in lithium tantalate crystals through multiple scanning with infrared laser irradiation. This ordering effect was attributed to domain formation and growth under the influence of alternating pyroelectric field during heating and cooling processes. Circular domains appeared due to 1D to 2D shape transformation and grew by merging with newly formed domains during subsequent scanning. The ordering of the domain pattern was characterized by an increase in the autocorrelation function peak, indicating domain interaction. This mechanism was confirmed through computer simulation based on the analogy between domain and crystal growth. The discovered domain ordering effect bears similarity to similar effects in magnetic materials.

Summary: High recoverable energy storage density (W-rec) and high energy storage efficiency (eta) are urgently needed for their potential application in pulse capacitor devices. However, low eta and breakdown strength (BDS) have hindered the achievement of high W-rec at high electric field. In this study, Bi(Mg0.5Ti0.5)O-3 (BMT) was introduced into Ba(Ti0.92Sn0.08)O-3 (BTS) matrix to enhance the relaxor character and reduce electrostrictive strain. The results showed significantly improved BDS and a high W-rec of 4.34 J/cm(3) with excellent temperature stability.

Summary: Lithium-niobate-based waveguides are important platforms for integrated optical technologies. In this paper, we propose a method for creating an integrated optical frequency conversion device using focused ion beam (i-beam) periodical poling technique after the soft proton exchange (SPE) process. The study reveals that the SPE process leads to the formation of shallow isolated nanodomains, which is preferable for periodical poling. We successfully create a high-quality 2-μm-period domain structure in a channel waveguide.

Summary: We studied the electronic transport and resistive switching phenomena in polycrystalline bismuth ferrite using advanced conductive atomic force microscopy (CAFM). Contrary to many macroscopic methods, we demonstrate that resistive switching in bismuth ferrite is caused by pure electronic processes of trapping/releasing electrons and injection of electrons by the scanning probe microscopy tip. The electronic transport is comprehensively described by the combination of the space charge limited current model, while the presence of a built-in subsurface charge makes the Schottky barrier at the interface less important.

Summary: The influence of (K0.5Bi0.5)TiO3 (KBT) dopants on crystal and microstructure, ferroelectric and dielectric properties of ceramic composition from morphotropic phase boundary in the system (1-x-y)(Na0.5Bi0.5)TiO3 - xBaTiO(3) - y (K0.5Bi0.5)TiO3 (x = 0.06, y = 0-0.15) modified by ZnO additives was investigated. Changes in the volume-weighted crystallite size distribution function G(L) from 42.8 nm to 62.6 nm were observed. The microstructure and second harmonic generation data indicated a change in the relative content of polar nanoregions in tetragonal nonpolar matrix. The temperatures of phase transitions T (m) and T (d) decreased with an increase in KBT concentration.

Summary: Knowledge of the statics and dynamics of ferroelectric domains is crucial for understanding macroscopic polarization and strain. In this study, piezoresponse force microscopy (PFM) is used to investigate field-induced phase transitions and local switching properties in a (1-2x)Na0.5Bi0.5TiO3-xBiFeO(3)-xPbTiO(3) system. Rietveld analysis of x-ray diffraction data reveals the crystallization of the compound in single and dual phases for the chosen compositions. The study finds a phase transition from relaxor to normal ferroelectric behavior upon the application of a local electric field, with reversible behavior observed for higher values of x.

Summary: Halide perovskites (HPs) are revolutionary optoelectronic materials, and mixing A-site organic cations is a widely used strategy to optimize their properties. This study investigates the influence of different organic cations on the structural, thermal, and electrical properties of HPs. The results reveal that the charge transport properties are determined by the size of the A-site cation, while the structure and phase transitions are affected by the composition in an unusual manner. Thermal degradation tests show that not all mixed compositions are more stable than their pure counterparts, and the degradation kinetics may also depend on the substituent cation. This research improves our understanding of the characteristics of mixed perovskites with different organic cations.

Summary: A contactless technique is introduced for direct time-resolved measurements of the full dynamics of the adiabatic temperature change in electrocaloric materials. The technique detects the infrared radiation emitted by the electrocaloric sample with μs time resolution and mK temperature resolution. Time-resolved measurements of the electrocaloric effect are presented at kHz frequencies and small field strengths. The technique allows for the simultaneous recording of transient behaviors in the applied electric field and induced polarization, providing a comprehensive understanding of the correlation between electrocaloric and ferroelectric properties. Additionally, it can be used for continuous fatigue measurements for >10(6) electric field cycles.
