Superior self-powered infrared photodetector via semiconducting graphene-nanoribbons-based vertical heterojunctions

Applied Physics Reviews, Journal Year: 2025, Volume and Issue: 12(2)

Published: April 7, 2025

Self-powered photodetectors, operating without an external power source, have garnered extensive interest for infrared (IR) detection owing to their vast potential in low-power consumption sensor systems. Here, a short-wavelength (SWIR) heterojunction photodetector utilizing semiconducting graphene nanoribbons has been achieved and demonstrated record-high performance. In the self-powered mode, presents responsivity of 73.5 A/W detectivity 7.5 × 1014 Jones, surpassing previously reported IR photodetectors by several orders magnitude. The superior performance is primarily due enhancement electric field caused photogating effect at heterointerface. device also displays unparalleled −5 V bias voltage, achieving 843 A/W, 1015 quantum efficiency 105%, all which are record-breaking values SWIR date. Therefore, our approach provides new insight demonstrates great future high-performance technology.
