Recent advances in Raman spectroscopy for characterizing graphene, graphite, and carbon nanotubes are reviewed comparatively. We first discuss the first-order and the double-resonance (DR) second-order Raman scattering mechanisms in graphene, which give rise to the most prominent Raman features. Then, we review phonon-softening phenomena in Raman spectra as a function of gate voltage, which is known as the Kohn anomaly. Finally, we review exciton-specific phenomena in the resonance Raman spectra of single-wall carbon nanotubes (SWNTs). Raman spectroscopy of SWNTs has been especially useful for understanding many fundamental properties of all sp2 carbons, given SWNTs can be either semiconducting or metallic depending on their geometric structure, which is denoted by two integers (n,m).

- Progress, challenges, and opportunities in two-dimensional materials beyond graphene. (2013, methodology): “When varying the layer number between bulk, few, and single layers, the Raman spectra differ in spectral width and intensity due to differing interlayer interactions.(122,129) Substrates that have vibrational modes that overlap with those in the material of interest should be avoided.”
