A few‐layer MoS2 photodetector driven by poly(vinylidene fluoride‐trifluoroethylene) ferroelectrics is achieved. The detectivity and responsitivity are up to 2.2 × 1012 Jones and 2570 A W−1, respectively, at 635 nm with ZERO gate bias. Eg of MoS2 is tuned by the ultrahigh electrostatic field from the ferroelectric polarization. The photoresponse wavelengths of the photodetector are extended into the...
Ultrasensitive and broadband MoS2 photodetectors driven by ferroelectrics are developed by J. Wang, W. Hu, and co‐workers on page 6575. A high detectivity (≈2.2 × 1012 Jones), photoresponsitivity (2570 A W−1), and photoresponse wavelength (visible to 1.55 μm) detector is achieved under an ultra‐high electrostatic field from ferroelectric polarization.
