Surface-enhanced Raman spectroscopy (SERS) is a sensitive tool for studying processes occurring at solid/liquid, solid/gas interfaces. However, one limitation for this technique has been that the large enhancement of Raman signal is only obtainable on certain metals, mainly coinage metals. To apply SERS to other surfaces, an overlayer SERS strategy has been developed. In this presentation, an overview of overlayer SERS will be given and new results will be used to demonstrate the applicability of this tactic to a variety of materials of significance to chemical processes, such as catalysis, chromatography separation, photochemistry, and ultrathin optoelectronic material processing.
