Machine‐Learning‐Assisted Understanding of Depth‐Dependent Thermal Conductivity in Lithium Niobate Induced by Point Defects

Advanced Electronic Materials, EarlyView.
Thermal conductivity, a fundamental property of lithium niobate, plays a pivotal role in determining its device performance. By integrating experiments with machine‐learning‐assisted simulations, this study demonstrates that oxygen vacancies induced by thermal reduction result in a pronounced suppression of thermal conductivity and a marked depth ...

Encapsulated Organohydrogel Couplants for Wearable Ultrasounds

Advanced Electronic Materials, EarlyView.
Hydrogels are ideal for wearable ultrasonic devices but suffer from water loss during long‐term monitoring. Adding excessive glycerol increases attenuation, while elastomer encapsulation causes uneven interfaces due to shrinkage and scattering acoustic waves.

ULF Multi‐Key Tunable Magnetoelectric Antenna Array with Enhanced Communication Data Rate

Advanced Electronic Materials, EarlyView.
This work presents a reconfigurable magnetoelectric antenna with a dual‐asymmetric cantilever structure. By adjusting its fixed boundary conditions, the antenna's resonant frequency is tunable over a 500 Hz range within the ultra‐low‐frequency (ULF) band.

On the Enhanced p‐Type Performance of Back‐Gated WS2 Devices

Advanced Electronic Materials, EarlyView.
A scalable method for directly growing WS2 enables robust and persistent p‐type behavior in back‐gated FETs, independent of metal contacts, thickness, or ambient conditions. Electrical measurements reveal minimal Schottky barrier heights and stable thermionic transport, while first‐principles simulations suggest tungsten vacancies or WO3 species as the
