Graphene's entire Raman spectrum, including dispersive and fixed bands, missing bands not forbidden by symmetries, weak bands, overtone bands, Stokes anti-Stokes anomalies, individual bandwidths, trends with doping, and D-2D band spacing anomalies emerge naturally and directly in KHD theory....
The Raman spectrum of the buffer layer remains visible after the growth of one monolayer on top but, despite the relatively low absorption coefficient of graphene, the Raman intensity is strongly reduced (typically divided by 3). The buffer layer background will bias usual evaluations of the ...

We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers. The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the electron bands via a double resonant Raman ...

As in other sp2 carbons, the G′ feature in the Raman spectrum originates from the double resonance (DR) Raman process [61], [62], and links electrons and phonons in the graphene dispersion relations [20], [24], [25], [52], [63]. Resonance Raman studies: Probing electrons and ...
For Eu deposition, we also report on a redshift in the graphene Raman spectrum, possibly due to Eu-adsorption or Eu intercalation with the graphene lattice4. A preliminary analysis of photoresponse uncovers no correlation between photovoltage and surface potential, with the photovoltage values largely...
