Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Encapsulating Zinc Powder in MXene/Silk Scaffolds with Zincophilic‐Hydrophobic Polymer for Flexible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work develops flexible zinc‐ion batteries (FZIBs) using a zincophilic/hydrophobic polymer (thermoplastic polycarbonate‐based polyurethane, TPCU) to protect Zn powder anodes and MXene/Silk (MXS) as flexible current collectors. The designed TPCU‐ZnP@MXS structure enables uniform Zn deposition, yielding dendrite‐free anodes with stable cycling ...

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

Advanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...
