Quasi‐Antipolar Nanoclusters Driven Superior Energy Storage in High‐Entropy Relaxor Ferroelectrics

open access: yesAdvanced Science, EarlyView.
Quasi‐antipolar nanoclusters are engineered in lead‐free NaNbO3‐based high‐entropy relaxors that weaken polar nanoregion coupling and induce distinct ferroelectric transition under high fields to enable desirable polarization response. This breakthrough system achieves ultrahigh recoverable‐energy‐density (≈18.3 J cm−3), efficiency (≈91.5%), and ...

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

open access: yesAdvanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

High energy storage performance of (Na0.5Bi0.5)TiO3 thin film induced by stress engineering

open access: yesJournal of Materiomics
Relaxor ferroelectrics are the primary candidates for high-performance energy storage dielectric capacitors. Here, stress engineering, which was realized by optimizing the lattice mismatch between (Na0.5Bi0.5)TiO3 film and SrRuO3/(La0.5Sr0.5)CoO3 bottom ...

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

open access: yesAdvanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Molecular Sieve Promoted Growth of Ferroelectric Trilayer 3R‐MoS2 for Polarization‐Dependent Reconfigurable Optoelectronic Synapses

open access: yesAdvanced Science, EarlyView.
The noncentrosymmetric trilayer rhombohedral‐stacked MoS2 nanoflakes with enhanced sliding ferroelectric properties are synthesized via a molecular sieve‐assisted chemical vapor deposition process. The switchable polarization states, combined with the exceptional light/gate voltage modulated electrical properties of these nanoflakes, enable broadband ...

Local structural changes associated with relaxor behavior in Sn-doped BaTiO_{3}

open access: yesPhysical Review Research
Polar nanoregions (PNRs) play an important role in relaxor ferroelectrics. Despite decades of research, structural understanding of their formation is lacking. In this study, we investigate how PNRs form by using Ti K-edge x-ray absorption fine structure
