Molybdenum disulfide nanostructures coupled with metal plasmonics for improved electronic and photonic performances

Abstract

Low-dimensional molybdenum disulfide (MoS₂) possesses great potential in many fields due to its intriguing optical, electronic and catalytic characteristics. In the last decade, the preparation, property studies and emerging multi-functional applications of MoS₂-based hybrids have attracted considerable attention. It is crucial for composites to overcome the limitation of individual MoS₂ materials. Meanwhile, the relationship between metal (Au, Ag, Bi, etc.) plasmonic nanostructures and MoS₂ is closely connected, and their emerging characteristics have been studied based on the bottom-up synthesis of hybrid materials, as well as the assembly of different prefabricated components. Significantly, several intrinsic drawbacks of MoS₂ nanostructures may be addressed after the integration of MoS₂ and nano-plasmonics has been remarkably achieved. MoS₂ nanostructures with diverse characteristics are improved by the plasmonic metal nanomaterials. Due to the importance of the integrated MoS₂ and metal plasmonics, the recent synthesis routes of hybrids are comprehensively presented. More importantly, on the basis of their improved electronic and photonic characteristics, the expanded applications of MoS₂ and plasmonics nano-hybrids, such as sensing, catalysis, electronic devices and biomedicine, are also included in this review.
