Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry

Advanced Functional Materials, EarlyView.
A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

Production and Characterization of ZrO2-Si3N4 Ceramics

Gazi Üniversitesi Fen Bilimleri Dergisi
ZrO2-Si3N4 ceramics (Si3N4 content varies between 0-20 wt.%) were produced 1500°C under a nitrogen atmosphere. As the amount of Si3N4 in ZrO2 was increased, densification was inhibited and the bulk density decreased gradually.

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...
