Abstract / Description: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 area.
