Morphotropic Phase Boundary in Graft Poly(Vinylidene Fluoride‐co‐Tetrafluoroethylene) With High Curie Temperature

Advanced Science, EarlyView.
The first TrFE‐free ferroelectric polymers exhibiting concurrently a morphotropic phase boundary and high Curie temperature are reported through a grafting strategy, which is completely different from previous methods to design MPB by composition and irradiation. This finding offers a cost‐effective solution to decode the long‐standing inverse relation

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

Advanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

Local Polarization Unit Engineering Enables Ultrahigh Energy Density in NBT‐Based High‐Entropy Ceramic Capacitors

Advanced Science, EarlyView.
Herein, we demonstrate a breakthrough in dielectric energy storage by engineering local polarization units in high‐entropy multilayer ceramic capacitors (MLCCs). The optimized MLCCs achieve an ultrahigh recoverable energy density of 18.2 J cm−3 with 91% efficiency, coupled with exceptional thermal stability and fatigue resistance.

Large‐Scale Growth of Self‐Poled Ferroelectric Rashba Semiconductor α‐GeTe(111) Thin Films: A Crucial Step Towards Future CMOS‐Compatible Ferroelectric Spintronic Devices

Advanced Science, EarlyView.
Ferroelectric Rashba semiconductors promise ultralow‐power devices but lack industry‐quality films. This work demonstrates CMOS‐compatible fabrication of high‐quality α‐GeTe(111) films via magnetron sputtering, enabled by a 5 nm Sb2Te3 seed layer. Structural and ferroelectric analyses show robust, switchable polarization comparable to MBE films, paving

Outstanding TC Enhancement in 5d–3d Y2NiIrO6 by Compression

Advanced Science, EarlyView.
Double perovskite Y2NiIrO6 with half filed 3d eg–5d t2g configuration, exhibits first experimental example of pressure‐enhanced magnetic interaction in iridate and iridate‐related systems. Its Curie temperature increase from 192 to 243 K at 17 GPa. Herein, the orthogonal eg–t2g pathway remains robust even under compression‐induced lattice distortion ...

Influence of Bottom Electrodes on the Ferroelectric Stability of AlScN Film at High Temperatures

Advanced Electronic Materials, EarlyView.
The thermal stability of AlScN depends on the bottom electrode. When the bottom electrode possesses compressive stress, tensile strain develops in the AlScN upon thermal annealing, reducing the switching barrier. When the bottom electrode forms a coherent interface with AlScN, significant tensile strain and defects are generated in the AlScN layer ...
