Abstract

Abstract : 2D nonlayered semiconductors attract intense interest due to their unique planar structure and various fascinating optoelectronic properties. Here, a method is developed to design orientation‐controlled and well‐defined single‐crystalline PbS nanoplates arrays on mica. Furthermore, the single PbS nanoplate device displays great photoresponsivity, detectivity, and photogain values as high as 1621 A W −1, 1.72 × 10 11 Jones, and 2512, respectively.
