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<sup>-1</sup> , 1.72 × 10<sup>11</sup> Jones, and 2512, respectively.
