説明
The surface-enhanced Raman scattering (SERS) of graphene on SiC with Au nanoparticles makes it possible to identify the spectrum of a buffer layer, which is a non-conductive carbon layer located between graphene and SiC, as well as that of graphene. In conventional Raman scattering spectroscopy, SiC peaks are superimposed on the peaks of the buffer layer and the G peak of graphene, which prevents investigation of the spectra of the buffer layer and graphene. We overcame these issues using the SERS effect and demonstrated that the peak positions of the buffer layer do not change with excitation wavelength. The excitation wavelength dependence of SERS enhancement coincided well with that of absorbance, indicating that an electromagnetic enhancement dominates the SERS effect. Our SERS method paves the way to evaluate the properties of the buffer layer as well as graphene on SiC.
