Residual Stresses and Micro‐voids Propel Metal Diffusion for Filament‐Based Memristors

Advanced Science, EarlyView.
Introducing non‐reactive nitrogen during silver sputtering enables low‐voltage (<60 mV) switching in memristors via nano‐void formation and residual stresses in the gigapascal range. This promotes sub‐micron filamentation and neuromorphic behaviors, including multi‐peak synaptic responses.

Versatile and Robust Reservoir Computing with PWM‐Driven Heterogenous R–C Circuits

Advanced Science, EarlyView.
A robust physical reservoir computing (PRC) system using pulse‐width modulation (PWM)‐encoded R–C circuits is introduced. By enabling customizable nonlinearities and timescales, this system achieves state‐of‐the‐art accuracy in chaotic, multiscale, and multiclass tasks while maintaining stability across temperature variations and device batches.

Ternary Inclusion Co‐Crystals for Efficient Photothermal Conversion and Solar‐Driven Water Evaporation

Advanced Science, EarlyView.
An inclusion co‐crystal strategy for elevating photothermal conversion efficiency is developed. A Tröger's base molecular box strongly bind two electron‐deficient TCNQ forming 1:2 ternary inclusion charge‐transfer co‐crystals, which displays a high photothermal efficiency of 94.3%.

Large Built‐in Fields and Tunable Ferroelectricity in Composition‐Graded ScAlN Thin Films Deposited by Reactive Sputtering

Advanced Science, EarlyView.
This study explores composition‐graded ScxAl1‐xN thin films grown by large‐scale and CMOS‐compatible sputtering that can effectively suppress abnormally‐oriented grains. Importantly, their ferroelectric properties can also be tuned owing to large built‐in fields induced by chemical/polarization gradient.

Low‐Frequency Noise Spectroscopy for Navigating Geometrically Varying Strain Effects in HfO2 Ferroelectric FETs

Advanced Science, EarlyView.
This study investigates the material and geometrically varying strain effects on HfO2 ferroelectric FETs (FeFETs). Through noise analysis, the reverse scaling effect is demonstrated due to the strain effects in the FeFET structure. This result indicates the importance of strain engineering in the FeFET for optimized performance.
