Abstract
The size and density of Ag nanoparticles on n-layer MoS2 exhibit thicknessdependentbehavior. The size and density of these particles increased anddecreased, respectively, with increasing layer number (n) of n-layer MoS2.Furthermore, the surface-enhanced Raman scattering (SERS) of Ag on thissubstrate was observed. The enhancement factor of this scattering varied withthe thickness of MoS2. The mechanisms governing the aforementioned thicknessdependences are proposed and discussed.
