title: Surface-enhanced Raman scattering of 4-aminobenzenethiol on gold: the concept of threshold energy in charge transfer enhancement.
abstract: 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.
