Catalytic Electron‐Driven Non‐Equilibrium Phase Transition in Quantum Electronic Heterostructures

Advanced Science, EarlyView.
This study proposes an innovative method to control the phase of heterostructured materials via electron flow manipulation. Leveraging this technique, a new topological phase is achieved that hosts excitons at the interface of a topological insulator.

Zirconium‐Rich Strategy in Ultrathin Hf0.5Zr0.5O2 toward Back‐End‐of‐Line‐Compatible Ferroelectric Random Access Memory

Advanced Science, EarlyView.
Here, the zirconium‐rich layer (Zr‐RL) strategy is developed in terms of ferroelectric (FE) properties, microstructure, switching kinetics, and reliability. Compared to the FE capacitor with conventional HZO film, the sub‐6 nm HZO/Zr‐RL/HZO stack exhibits a significantly low annealing temperature, an ultra‐low Vop, and an excellent ferroelectricity ...

Chemically‐Disordered Transparent Conductive Perovskites With High Crystalline Fidelity

Advanced Science, EarlyView.
Kinetically arrested, chemically disordered perovskite thin films exhibit exquisite crystalline fidelity, broad IR–UV transparency, and low resistivity, despite incorporating five mismatched 3d–5d cations, including Cr and W. This study unites electronic correlation, cation diversity, valence complexity, and disorder—enabling new transparent conductors

Excellent energy storage performance in Bi0.5Na0.5TiO3-based lead-free high-entropy relaxor ferroelectrics via B-site modification

Journal of Advanced Ceramics
Next-generation advanced high/pulsed power capacitors urgently require dielectric materials with outstanding energy storage performance. Bi0.5Na0.5TiO3-based lead-free materials exhibit high polarization, but the high remanent polarization and large ...

Chain Topology Engineering in Amphiphilic Block Copolymers: Crosslinking‐Induced Nanodomain Refinement for Ultrahigh Energy Density under Extreme Conditions

Advanced Science, EarlyView.
An amphiphilic block copolymer is constructed via self‐assembly‐induced nanoscale microphase separation. A crosslinker with dual electron‐withdrawing groups (─CF3/─O─) is introduced to refine the PEA phase domain. The crosslinking film achieves record‐high energy densities of 11.07 J cm−3 (150 °C/700 MV m−1) and 6.45 J cm−3 (200 °C/600 MV m−1) with an ...

Coexisting Phases in NaNbO3 Thin Films Influenced by Epitaxial Strain and Size Effects

Advanced Science, EarlyView.
Coherently strained NaNbO3 thin films are synthesized across a range of thicknesses, enabling the study of size effects under epitaxial strain in antiferroelectric thin films without relaxation. Competing antiferroelectric‐ferroelectric phases are observed, leading to the stabilization of phase coexistence, multistate switching with strong retention ...

Order–Disorder Phase Stabilization by Pressure‐Induced Charge Transfer Enhances the Ferroelectric Photovoltaic Effect in Multiferroic BaFe4O7

Advanced Science, EarlyView.
A pressure‐driven charge transfer in multiferroic BaFe4O7 induces Fe valence disproportionation and structural distortion, drastically narrowing the bandgap and enhancing ferroelectric polarization. This synergistic optimization boosts photocurrent 2.5‐fold and is retained upon decompression, offering a promising strategy to overcome the ferroelectric ...

Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic–Ferroelastic Multiferroics and Anomalous and Spin Transport

Advanced Science, EarlyView.
Li‐ and V‐intercalated V2Se2O bilayers possess intralayer ferrimagnetic and interlayer ferromagnetic orders, alongside ferroelasticity, in‐plane uniaxial magnetic anisotropy, half‐metal/enhanced spin splitting, the anomalous Hall effect, giant magnetoresistance, tunneling magnetoresistance, near‐perfect spin filtering effect, spin Seebeck effect, and ...
