Multifunctional Vertical Bulk‐Heterojunction Transistors With Amorphous GaOx for Neuromorphic Perception‐to‐Decision

Advanced Science, EarlyView.
A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.
