Abstract

The seamless combination of plasmonic structures with metal oxides and in particular with 2D materials has attracted significant recent interests. Here, a novel approach to grow molybdenum disulfide (MoS2) is presented: an optically active 2D material, directly onto plasmonic nanoscale gold disks via a surface diffusion delivery of Mo from within the nanostructure and a sulfidation process. X-ray photoelectron spectroscopy and Raman spectroscopy measurements demonstrate the existence and the reaction process of few layered MoS2. Delivery of Mo from within the nanostructure and direct growth of MoS2 has the potential to form better defined metal/MoS2 interfaces compared to exfoliation routes. This facile approach has the potential for application in photodetector or other devices.
