Achieving giant electrostrain of above 1% in (Bi,Na)TiO3-based lead-free piezoelectrics via introducing oxygen-defect composition

Huajie Luo et al.

Summary: We propose an innovative strategy based on defect chemistry to achieve a giant strain of 1.12% in lead-free Bi0.5Na0.5TiO3 (BNT)-based ceramics by forming a defect-engineered morphotropic phase boundary. The incorporation of the hypothetical perovskite BaAlO2.5 with oxygen defect into BNT leads to strongly polarized directional defect dipoles, resulting in a strong pinning effect after aging. The large asymmetrical strain is mainly attributed to the aligned defect dipoles along the crystallographic [001] direction destroying the long-range ordering of the ferroelectric and promoting reversible phase transition and polarization rotation.

Domain evolution and coercive field reduction in rhombohedral (Na0.5Bi0.5)TiO3-based crystals by alternating electric field

Huangfu Geng et al.

Summary: This study proposes a simple method to significantly reduce the high coercive field (Ec) of rhombohedral (Na0.5Bi0.5)TiO3-based crystals through domain engineering. By applying an alternating current (AC) electric field, the Ec of Mn-doped (Na0.485K0.015Bi0.5)TiO3 single crystal can be reduced from 70 to 20 kV/cm without sacrificing the ferroelectric polarization. The laminar domain configuration formed by AC cycles greatly reduces the required energy for polarization reversal and maintains low Ec even after depolarization at 250 degrees C.

Investigation of lattice evolutions of tetragonal (Na0.5Bi0.5)TiO3-BaTiO3 single crystal by phonon modes in Raman scattering

Geng Huangfu et al.

Summary: In-situ polarized Raman scattering was used to study the lattice structure evolutions induced by temperature and electric field in (1-x%)(Na0.5Bi0.5)TiO3-x%BaTiO3 (NBT-xBT) relaxor ferroelectrics. It was found that electric field cannot induce ferroelectric state after the disappearance of frequency dispersion, indicating a competition between relaxor characteristics and long-range ferroelectric order with temperature. Additionally, no P4bm-P4mm transition was observed under high electric fields. This work explains the Raman scattering and lattice evolutions of NBT-8BT and proposes a method for analyzing Raman spectrum that is generally applicable to other ferroelectrics.

Direct observations of electric-field-induced domain switching and phase transition in 0.95Na0.5Bi0.5TiO3-0.05BaTiO3 single crystals using in situ transmission electron microscopy

Hai Liu et al.

Summary: This study directly observed the electric-field-induced domain switching and phase transition in lead-free 0.95Na(0.5)Bi(0.5)TiO(3)-0.05BaTiO(3) (NBT-BT) single crystals using in situ transmission electron microscopy. The findings demonstrate the significant role of these processes in enhancing the macroscopic properties. These insights contribute to understanding the structural evolution and microstructural mechanism of macroscopic piezoelectric behaviors near the morphotropic phase boundary (MPB) in NBT-based materials.

Ann-Katrin Fetzer et al.

Summary: This study investigates the evolution of nanoscale structures and their association with ferroelectric domains in relaxor ferroelectrics using conventional and scanning transmission electron microscopy. The results show the presence of different types of nanodomains in samples with different compositions, and the distribution of these nanodomains varies with the composition.

Atomic-scale insight into the tetragonal platelets correlated with the antiferroelectricity in Na0.5Bi0.5TiO3-based materials

Hai Liu et al.

Summary: The structural origin of antiferroelectric (AFE)-like double P-E loops near the depolarization temperature in lead-free Na0.5Bi0.5TiO3 (NBT)-based materials has been investigated. It was found that the AFE-like behavior in Mn: NBT single crystals is strongly related to the tetragonal phase. Tetragonal platelets with a thickness of 1-2-unit cells were observed at the atomic level and AFE-like dipoles were formed by two antiparallel-polarized tetragonal platelets separated by a thin non-polar and tilt-free transition layer. This study provides important atomic-scale information and reveals an unobserved AFE-like structure in NBT-based materials.

Guangzhi Dong et al.

Summary: The study fabricated a novel solid solution ceramic with relaxor ferroelectric features using high temperature solid-state reaction method. The ergodic composition showed large repeatable electrostrain value and high piezoelectric stain coefficient, while the non-ergodic compositions exhibited unrepeatable large strain response. The research aims to guide the design of lead free relaxor ferroelectric materials with desired electrostrain properties.

Nanoscale bubble domains with polar topologies in bulk ferroelectrics

Jie Yin et al.

Summary: The authors demonstrate the achievement of self-confined bubble domains with multiple polar topologies, especially skyrmions, in bulk Bi0.5Na0.5TiO3 ferroelectrics. The phenomenon is driven by the interplay of bulk, elastic, and electrostatic energies of coexisting modulated phases. This leads to reversible and donut-like domain morphology evolution in the material.
