Webb13 mars 2024 · Consequently, unlike the presence of a monolayer graphene, which has a single Raman shift at 2700 cm −1, the broadening in this study indicates the presence of a multi-layered structure. Additionally, the oxygen-based functional groups prevent efficient stacking of the graphene layers, causing a slight shift in the peak appearance [ 46 ]. Webbför 2 dagar sedan · In the application of WS2 as a surface–enhanced Raman scattering (SERS) substrate, enhancing the charge transfer (CT) opportunity between WS2 and analyte is an important issue for SERS efficiency.
