Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

Advanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting

Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

Advanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Solution Processed Polymer Source‐Gated Transistors for Zero‐Power Photosensing

Advanced Electronic Materials, EarlyView.
This study demonstrates the first solution‐processed bulk heterojunction organic source‐gated transistors (OSGTs) and photo‐OSGTs fabricated using DPP‐DTT: PCBM. Copper‐electrode OSGTs show deep off‐state at zero gate‐source voltage, channel length‐independent on‐state current, and low voltage saturation (γ = 0.22).
