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.

基质扩散传递的钼直接将几层MoS2整合到等离子金纳米结构上

等离子激元结构与金属氧化物，尤其是与2D材料的无缝结合引起了人们的极大兴趣。在这里，提出了一种新的生长二硫化钼（MoS ₂）的方法：一种光学活性的2D材料，通过从纳米结构内部进行Mo的表面扩散输送和硫化过程，直接将其沉积在等离子纳米级金盘上。X射线光电子能谱和拉曼光谱测量证明了少数MoS ₂层的存在和反应过程。从纳米结构内传递Mo并直接生长MoS ₂具有形成更好定义的金属/ MoS ₂的潜力界面与剥离路径相比。这种简便的方法具有在光电探测器或其他设备中应用的潜力。
