Summary: The study demonstrates that the ferroelectric properties and crystalline structure of pure zirconia thin films are influenced by film thickness, with an increase in thickness leading to a higher m-phase fraction. Futhermore, a phase transition from orthorhombic to cubic and tetragonal phases was observed as the thickness increased.

Summary: This study reveals the mechanism of resistance degradation in lead-free alternative KNN thin films, finding that the conduction mechanism is Schottky-limited and the resistance degradation is accompanied by the interfacial accumulation of additional charged defects and a reduction in Schottky barrier height. The results show that oxygen vacancies accumulate in the field-up polarity and multiple defects, potentially oxygen vacancies and holes trapped by potassium vacancies, accumulate in the field-down polarity. By measuring different film samples, it is found that the natural logarithm of leakage current is linearly proportional to the defect concentration to the power of 0.25.

Summary: LiFe5O8/Ba0.6Sr0.4TiO3 (LFO/BST) composite films were fabricated via chemical solution deposition method, where the internal electric field could be established inside the film owing to the lithium ions' de-intercalating effect of LiFe5O8 (LFO) layer under the bias field. Thus, we successfully achieved a high dielectric tunability and low loss in the composite films.

Summary: Ce-doped indium oxide (ICO) films were prepared via reactive plasma deposition, and the impact of annealing temperature and time on the electrical, optical, and structural properties of the films was investigated. The results showed that annealing treatment improved the crystallinity, grain size, transmittance, and reduced resistivity of the ICO films. Annealing at 210 degrees C in air for 50 min yielded films with a mobility of 93.3 cm²/V s, carrier concentration of 2.48 x 10²⁰/cm³, average transmittance of 86.5%, and resistivity of 2.6 x 10⁻⁴ Ω·cm. The ICO films exhibited higher carrier mobility and lower carrier concentration compared to Sn-doped In₂O₃ (ITO) films, which is favorable for enhancing the efficiency of solar cells.

Summary: This study investigates the relationship between composition segregation and ultrasonic transducer performance in lead magnesium niobate-lead titanate (PMN-PT) single crystals. The results show that changes in crystal composition significantly affect the piezoelectric coefficient and relative permittivity, but have minimal impact on the transducer bandwidth and center frequency. By using crystals of different compositions, similar transducer performance can be achieved, reducing material costs.

Summary: Lead-free bismuth sodium titanate (BNT) ceramics with a composition of x = 3.5 demonstrate a large strain response of 0.61%. The coexistence of ferroelectric and relaxor domain structures, along with the substitution of antiferroelectric NN, contribute to the enhanced strain response. This study provides new insights into the interplay between mesoscopic domains and macroscopic electrical properties in BNT-based piezoceramics.

Summary: (Na1/2Bi1/2)TiO3-based piezoelectric multilayer actuators (MLAs) have attracted attention as a replacement for lead-based piezoelectric devices due to environmental concerns. In this study, a grain orientation engineering approach was used to prepare a textured NBT-based MLA with high strain output and effective co-firing. The textured MLA achieved a high texturing degree and significantly higher strain performance compared to the non-textured counterpart. The effects of grain orientation engineering on mechanical properties and fracture behavior were analyzed.

Summary: In this study, neutron atomic pair distribution function (PDF) analysis was used to investigate the local-structural features of relaxor-ferroelectric materials at low temperatures. The results revealed that the existence of polar nanoregions (PNRs) is characterized by strong displacement correlation rather than structural symmetry. This finding provides a better understanding of the high-performance piezoelectric properties of these materials.

Summary: Lead zirconate (PZ)-based antiferroelectric (AFE) materials have limitations due to their ultrahigh critical electric field (EF). To overcome this, a bismuth-based perovskite, Bi(Zn2/3Nb1/3)O-3 (BZN), was introduced to PZ to form the PZ-BZN solid solution. Single crystals of this system were grown and investigated, revealing improved energy storage performance and a better understanding of the domain structure and origin of the intermediate (IM) phase in PZ-based AFE materials.
