O Radical‐Induced n‐to‐p Transition in PbS Quantum Dots Enabling Enhanced and Stable Photogating in QD/IGZO SWIR Phototransistors

ABSTRACT Colloidal PbS quantum dots (QDs) are promising photosensitizers for short‐wave infrared phototransistors. But their photogating efficiency is limited by unfavorable energy band alignment and interfacial defects. Here, we report an O radical exposure to induce an effectiv...
