Application of chiral WS₂ rolls in circular/linear polarization-sensitive photodetectors

We have fabricated chiral WS₂ rolls that utilize a chiral superstructure to address the lack of chirality in traditional two-dimensional materials. This structure exhibits responsiveness to both linearly polarized light and circularly polarized light. This unique combination enables the development of circular/linear polarization-sensitive photodetectors. Our data demonstrate that chiral WS₂ rolls exhibit robust linear/circular polarization responsiveness. Compared to traditional circular/linear polarization-sensitive photodetectors, this approach simplifies device fabrication and miniaturization, making it a promising optoelectronic material. The ability to effectively detect both linearly polarized light (LPL) and circularly polarized light (CPL) enhances the versatility of these devices, paving the way for innovative applications in optical sensing and communication. Overall, chiral WS₂ rolls represent a significant advancement in the field of optoelectronics, offering potential improvements in performance and functionality.
