TLDR
This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.Abstract:
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality 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 process The G peak slightly down-shifts This allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research arearead more

Electron and Phonon Properties of Graphene: Their Relationship with Carbon Nanotubes
TL;DR: In this paper, the authors review the exciting news about the electronic and phonon states of graphene and suggest how these discoveries help understand the properties of carbon nanotubes, and also show that the Born-Oppenheimer principle breaks down for doped graphene.
