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 ...

Unrevealing the Carrier Dynamics Behavior of Cu–In–Zn–S‐Based Quantum Dot Light‐Emitting Diodes by Transient Electroluminescence Spectroscopy

Advanced Physics Research
The device performance of Cu–In–Zn–S (CIZS)‐based quantum‐dot light‐emitting diodes (QLEDs) still lags far behind CdSe‐based QLEDs, which mainly arise from unique trap‐related recombination in the CIZS quantum dots (QDs).
