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
