title: Fabrication of Ultrathin Bi2 S3 Nanosheets for High-Performance, Flexible, Visible-NIR Photodetectors.
abstract: Ultrathin Bi2 S3 nanosheets with thicknesses down to 2.2 nm are fabricated. The resultant ultrathin Bi2 S3 -based photoconductor shows high sensitivity to visible-near infrared light from 405 to 780 nm with a high external photoresponsivity up to 4.4 A W(-1) , high detectivity of ≈10(11) Jones, relatively fast response time of ≈10 μs, and high flexibility and durability.
