Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

open access: yesAdvanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

Li‐Well ZnO Memtransistors: High Reliability for Neuromorphic Applications

open access: yesAdvanced Materials, EarlyView.
A novel lithium (Li)‐well ZnO memtransistor integrates transistor switching and nonvolatile memory, akin to ferroelectric field‐effect transistors (FeFETs) and floating gates, while enabling low‐power operation via Li⁺ ion migration. Li⁺ ion migration and switching mechanisms were confirmed by 3D secondary ion mass spectrometry (SIMS).
