Enhanced Raman Scattering in CVD-Grown MoS2/Ag Nanoparticle Hybrids
Surface-Enhanced Raman Spectroscopy (SERS) is a powerful, non-destructive technique for enhancing molecular spectra, first discovered in 1974. This study investigates the enhancement of Raman signals from single- and few-layer molybdenum disulfide (MoS<sub>2</sub>) when interacting with silver nanoparticles. We synthesized a MoS<sub>2</sub> membrane primarily consisting of monolayers and bilayers through a wet chemical vapor deposition method using metal salts. The silver nanoparticles were either directly grown on the MoS<sub>2</sub> membrane or placed beneath it. Raman measurements revealed a significant increase in signal intensity from the MoS<sub>2</sub> membrane on the silver nanoparticles, attributed to localized surface plasmon resonances that facilitate SERS. Our results indicate that dichalcogenide/plasmonic systems have promising applications in the semiconductor industry.
