Abstract:
The discovery of surface enhanced Raman scattering (SERS) in the mid-1970s impacted on the surface science community because of its remarkably high and unique surface sensitivity. Surface roughness in scale of 10~100 nm have been found necessary to produce the giant SERS signal. In this paper we will show that SERS is indeed one of the important phenomena not only in surface science but also in nanoscale science[1].
