Advanced Electronic Materials, EarlyView.A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Photoresponse Properties of Ambipolar Transport in WSe2 Field‐Effect Transistors
Advanced Electronic Materials, EarlyView.This study explores the photoresponse of WSe2 ambipolar field‐effect transistors, which exhibit unipolar, saturation, and ambipolar transport regions. Light illumination induces a shift of critical voltage with enhanced photocurrent generation driven by the photogating effect without the material degradation seen in avalanche photodetectors. This study
