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

TL;DR: It is shown that graphene deposited on a substrate has a non-negligible density of atomic scale defects and the effect of such impurities on electron transport is evaluated by mimicking them with hydrogen adsorbates and measuring the induced changes in both mobility and Raman intensity.

TL;DR: A study of intravalley and intervalley double-resonance Raman processes mediated by static potentials in rotationally stacked bilayer graphene is presented and the peak properties depend on the mismatch rotation angle and can be used as an optical signature for superlattices in bilayers graphene.
