Cavity array, with excellent optical capture capability, has received increasing attention for the surface-enhanced Raman spectroscopy (SERS)-active substrates. Here, we proposed molybdenum disulfide (MoS ) nanocavities growing on pyramid Si (PSi) composed of in situ reduced Au nanoparticles (AuNPs)...
