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 (MoS 2 ) 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 MoS 2 . Delivery of Mo from within the nanostructure and direct growth of MoS 2 has the potential to form better defined metal/MoS 2 interfaces compared to exfoliation routes. This facile approach has the potential for application in photodetector or other devices.
