… Some threshold energy is required for 4-aminobenzenethiol to occupy the gold surface
sites capable of leading to the appearance of surface-enhanced Raman scattering peaks
via a charge transfer resonance enhancement mechanism. … Noble metallic
nanostructures exhibit a phenomenon known as surface-enhanced Raman scattering (SERS)
in which the scattering cross sections are dramatically enhanced for molecules adsorbed
thereon. In recent years, it has been reported that even single molecule … In this work, the …
