Special Issue Information

Dear Colleagues,

Ferroelectric materials, characterized by electrically switchable polarization, have found broad and mature applications in conventional transducers, actuators, and sensors in modern society. Recently, novel ferroelectric materials, made available by advanced synthesis techniques such as freestanding epitaxial thin films, nanometer/sub-nanometer nanoparticles/nanowires, organic ferroelectrics, and 2D van der Waals (vdW) ferroelectrics, have found applications in low-energy electronics and renewable energy. For example, based on the atomic thicknesses and complementary metal-oxide-semiconductor (CMOS) compatibility of 2D vdW ferroelectrics, ferroelectric materials can be used for post-Moore’s law nanoelectronics, including beyond-Boltzmann transistors, nonvolatile memories, and photoelectronic devices. Based on the polymer-like flexibility of ferroelectric nanowires, nanoferroic materials have found new applications in piezocatalysis for water splitting.

It is clear that the future holds great promise for the use of ferroelectric materials in novel applications. This Special Issue aims to showcase the latest advancements in ferroelectric materials and their diverse applications in various fields. We welcome contributions related to the synthesis and characterization of novel ferroelectrics, theoretical studies exploring new physics and functionalities, and nanoelectronic device developments involving vdW ferroelectrics.

The poly (vinylidene fluoride–trifluoroethylene–chlorofluoroethylene) P(VDF-TrFE-CFE) terpolymer has been identified as a promising candidate for the effective conversion of low-frequency mechanical vibrations into electricity. In this study, we provide a comprehensive and systematic investigation of the solvent-dependent mechanical, microstructural, electrical, frictional properties and triboelectric output performance of a relaxor ferroelectric P(VDF-TrFE-CFE) terpolymer. The P(VDF-TrFE-CFE) terpolymer films obtained from high dipole moment solvents have a longer rod-shaped grain than those from low dipole moment solvents. The crystallinity, Young’s modulus and dielectric constant of P(VDF-TrFE-CFE) terpolymer become larger as the dipole moment of solvents increases, while the remnant polarization remains almost the same. The P(VDF-TrFE-CFE) terpolymer film obtained from the highest dipole moment solvent generates almost 1.55 times larger triboelectric charge than that obtained from the lowest moment. We attributed this large difference to the greatly enhanced lateral friction of terpolymer film obtained from high dipole moment solvents. Full article

The study of the properties of ferroelectric materials against irradiation has a long history. However, anti−irradiation research on the ferroelectric domain has not been carried out. In this paper, the irradiation of switched domain structure is innovatively proposed. The switched domain of 700 nm lithium niobate (LiNbO3, LN) thin film remains stable after gamma irradiation from 1 krad to 10 Mrad, which was prepared by piezoresponse force microscopy (PFM). In addition, the changing law of domain wall resistivity is explored through different sample voltages, and it is verified that the irradiated domain wall conductivity is still larger than the domain. This domain wall current (DWC) property can be applied to storage, logic, sensing, and other devices. Based on these, a ferroelectric domain irradiation resistance model is established, which explains the reason at an atomic level. The results open a possibility for exploiting ferroelectric materials as the foundation in the application of space and nuclear fields. Full article

The polarization and elastrocaloric effect of chiral barium titanate (BaTiO3) with an Ising–Bloch-type domain wall under stress was investigated using the Landau–Ginzburg–Devonshire (LGD) theory. It has been shown that tensile stresses increase the magnitude of the Ising polarization component in barium titanate, together with a decrease in the domain wall width. Compressive stresses cause a reduction in the Ising polarization component and an increase in the domain width. Under compressive stress, barium titanate exhibits a negative elastrocaloric effect and temperature changes with increasing stress, while BaTiO3 exhibits a positive elastrocaloric effect under tensile stress. Bloch polarization shows angle-dependent polarization under external force, but the temperature change from the elastrocaloric effect is smaller than that of Ising polarization under stress. This work contributes to the understanding of polarization evolution under tension in ferroelectrics with chiral structure. Full article
