We report on a large decrease of surface-enhanced Raman scattering (SERS) of pyridine on cold and island Ag films due to Pd submonolayers. In contradistinction, it is shown that very thin (∼1 monolayer) Ag deposits give rise to SERS unobserved before the Ag deposition. Auger and reflectivity measurements are also presented.
