This photodetector shows ultra-sensitive detection at 6.5 pW in infrared, highlighting its potential for various applications.
We demonstrate a self-powered, high-speed InGaAs/ITO radial heterojunction nanowire array photodetector, achieving ultra-sensitive detection down to 6.5 pW at near-infrared, and single-pixel imaging under weak light illumination for a wide range of applications.
