Special Issue Information

Dear Colleagues,

Ferroelectric materials, characterized by their switchable spontaneous polarization, are playing an ever-increasing role in rapidly evolving technologies ranging from non-volatile information storage and mechanical-to-electrical energy conversion to high-power energy harvesting. The current materials landscape spans classical perovskite ferroelectrics, multiferroics, silicon-compatible hafnia-based ferroelectrics, ferroelectric semiconductors, and ferroelectric polymers, as well as emerging two-dimensional ferroelectric materials. As a central carrier, ferroelectric polarization can be effectively engineered across multiple length scales through strain and symmetry engineering, interface and defect control, compositional and dimensional design, and external fields, enabling unprecedented control over polar configurations, domain structures, switching kinetics, and cross-coupled responses.

This Special Issue, “Advanced Research on Ferroelectric Materials”, aims to provide a broad and forward-looking snapshot of this dynamic field. It welcomes contributions on ferroelectric oxide thin films and heterostructures, multicomponent bulk ceramics, two-dimensional and other low-dimensional ferroelectric materials, flexible and polymer-based systems, ferroelectric-related functional architectures, and so on. Topics include, but are not limited to, atomic-scale structural design, advanced structural characterization, and theory- and data-driven material exploration, as well as advanced dielectric capacitors, piezoelectric devices, negative-capacitance and ferroelectric memories, memristors, and neuromorphic computing. By assembling reviews, articles, and perspectives from materials science, condensed-matter physics, solid-state chemistry, and device communities, this collection seeks to bridge fundamental mechanisms with application-driven innovation and to inspire the next generation of ferroelectric materials and related technologies.

The formation and growth of isolated domains during local switching by a biased tip of a scanning probe microscope in a (100) cut of a bismuth titanate Bi4Ti3O12 single crystal were studied experimentally. The as-grown domain structure consists of two domain types: a-type (out-of-plane) and b-type (in-plane). Local switching of the a-type domain area leads to anisotropic growth of a hexagonal a-type domain (a-a switching) with 180° walls. The dependence of the domain size on the pulse duration during domain growth along the b-axis was considered in terms of the anisotropic current-limited domain wall motion. Local switching of the b-type domain area leads to formation of a hexagonal a-type domain (b-a switching) with 90° walls increasing in size linearly with the applied voltage. The dependence of the domain size on the pulse duration was measured over a wide range of humidities. The increase in the domain size at moderate humidity is attributed to the effect of the water meniscus. The decrease in the domain size at high humidity is attributed to backswitching under the action of the residual depolarization field, facilitated by a conductive water layer on the side surfaces of the sample. The obtained results provide useful insights into the domain kinetics of ferroelectrics with C2 symmetry and can pave the way for the development of domain engineering techniques. The obtained results establish a direct relationship between local switching kinetics, crystallographic anisotropy, and environmental conditions. This provides the scientific community with a new framework for understanding domain wall motion in multiaxial ferroelectrics, which is essential for the development of stable and reliable domain-engineered devices.
