Abstract:

Abstract Since the beginning of research on two-dimensional (2D) materials, a few numbers of 2D ferroelectric materials have been predicted or experimentally confirmed, but 2D ferroelectrics as necessary functional materials are greatly important in developing future electronic devices. Recent breakthroughs in 2D ferroelectric materials are impressive, and the physical and structural properties of twisted 2D ferroelectrics, a new type of ferroelectric structure by rotating alternating monolayers to form an angle with each other, have attracted widespread interest and discussion.

Abstract:

Ferroelectric nanostructures are attracting considerable attention due to their unusual physical properties and potential applications in memory devices and nanoelectromechanical systems. It has been found that low-dimensional ferroelectrics, such as ferroelectric nanodots, ferroelectric nanotubes and ferroelectric thin films, exhibit polarization vortices or vortex-like domain structures due to the strong depolarization field and the size effect. The polarization vortex is regarded as a new toroidal order in ferroelectrics which is different from the rectilinear order of polarization. The vor

Abstract:

Flexoelectric effect and its influence on the application of multifunctional ferroelectrics have been investigated. Theory of flexoelectric coupling has indicated that mechanical strain gradient can impact polarization in a way analogous to electric field. Experimentally, magnitudes of the flexoelectric coefficients have been measured in ferroelectric, incipient ferroelectric and relaxor ferroelectric perovskites. Present data of flexoelectricity suggests that such unconventional electromechanical coupling could make unique contribution to properly engineered ferroelectric thin films and nanos

Abstract Domain walls (DWs) in ferroelectrics are atomically sharp and can be created, erased, and reconfigured within the same physical volume of ferroelectric matrix by external electric fields. They possess a myriad of novel properties and functionalities that are absent in the bulk of the domains, and thus could become an essential element in next-generation nanodevices based on ferroelectrics. The knowledge about the structure and properties of ferroelectric DWs not only advances the fundamental understanding of ferroelectrics, but also provides guidance for the design of ferroelectric-ba

Abstract:

Among several different types of magnetoelectric multiferroics, "magnetically-induced ferroelectrics" in which ferroelectricity is induced by complex spin orders, such as spiral orders, exhibit giant direct magnetoelectric effects, i.e., remarkable changes in electric polarization in response to a magnetic field. Not a few spin-driven ferroelectrics showing the magnetoelectric effects have been found in the past decade.[1] However, their induced ferroelectric polarization is much smaller than that in conventional ferroelectrics and mostly develops only at temperatures much lower than room temp

Ferroelectrics are an integral component of the modern world and are of importance in electrics, electronics, and biomedicine. However, their usage in emerging wearable electronics is limited by inelastic deformation. We developed intrinsically elastic ferroelectrics by combining ferroelectric response and elastic resilience into one material by slight cross-linking of plastic ferroelectric polymers. The precise slight cross-linking can realize the complex balance between crystallinity and resilience. Thus, we obtained an elastic ferroelectric with a stable ferroelectric response under mechani

Thickness effect and mechanical tuning behavior such as strain engineering in thin-film ferroelectrics have been extensively studied and widely used to tailor the ferroelectric properties.

Ferroelectric materials are currently integrated in nonvolatile memory devices, whose principle is to allocate 0 and 1 logic bits to opposite orientations of the spontaneous polarization vector that are permitted by crystal symmetry.

On this background, we attempt to formulate new principles of exploiting such structural and operational degrees of freedom for unconventional applications of ferroelec

Ferroelectrics are very interesting materials for nonvolatile data storage due to the fact that they deliver very low power programming operation combined with nonvolatile retention. For 60 years researchers have been inspired by these fascinating possibilities and have tried to build ferroelectric memory devices that can compete with mainstream technologies in their respective time. The progress of the current concepts is limited by the low compatibility of ferroelectrics like PZT with CMOS processing.

Abstract:

Abstract2D ferroelectric materials with out‐of‐plane polarization are crucial for future nanoscale logic devices due to the increasing demand for energy‐efficient architectures in artificial intelligence. However, only a few 2D out‐of‐plane ferroelectrics are confirmed experimentally. As an important branch of ferroelectrics, organic–inorganic hybrid perovskite ferroelectrics show flexible structures, making them eligible for constructing multifunctional materials. Here, a 2D organic–inorganic hybrid perovskite ferroelectric (6‐BHA)2CdBr4 (6‐BHA is 6‐bromohexylamine) is designed, which crystal

Abstract:

Abstract Ferroelectrics are a kind of material with polar structure and the polarization direction can be inverted reversibly by applying electric field. They have attracted tremendous attention for their extensive applications in nonvolatile memory, sensors and neuromorphic computing. However, the conventional ferroelectric materials face insulating and interfacial issues in the commercialization process. In contrast, two-dimensional (2D) ferroelectric materials usually have excellent semiconductor performance, clean van der Waals interfaces and robust ferroelectric order in atom-thick layers

Abstract:

Abstract Two-dimensional (2D) van der Waals (vdW) ferroelectrics with switchable electric polarization offer exciting possibilities in the fields of physics, materials science, and device engineering. Beyond the conventional polarization-state regulation through electric-field, 2D ferroelectrics can offer important additional functionalities through isomeric phases, including paraelectric and antiferroelectric phases. In recent years, a variety of novel ferroelectric orders have been discovered in 2D materials, resulting from intra- or inter-layer symmetry-breaking. These hidden phases, exhibi

Abstract:

AbstractMolecular ferroelectric materials consist of organic and inorganic ions held together by hydrogen bonds, electrostatic forces, and van der Waals interactions. However, ionically tailored multifunctionality in molecular ferroelectrics has been a missing component despite of their peculiar stimuli-responsive structure and building blocks. Here we report molecular ionic ferroelectrics exhibiting the coexistence of room-temperature ionic conductivity (6.1 × 10−5 S/cm) and ferroelectricity, which triggers the ionic-coupled ferroelectric properties. Such ionic ferroelectrics with the absorbe

Depolarization effects induce distinct DW dynamics in normal and relaxor ferroelectrics, leading to deviations in energy barriers between DW velocity models and theoretical predictions.
