TL;DR: 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.

TL;DR: This work demonstrates a top-gated graphene transistor that is able to reach doping levels of up to 5x1013 cm-2, which is much higher than those previously reported.

TL;DR: It is demonstrated that graphite phonon dispersions have two Kohn anomalies at the Gamma-E(2g) and K-A'1 modes, and by an exact analytic derivation, it is shown that the slope of these kinks is proportional to the square of the electron-phonon coupling (EPC).

TL;DR: In this article, the position, width and intensity of G and D peaks at the edges are studied as a function of the incident light polarization, and the D-band is strongest for light polarized parallel to the edge and minimum for perpendicular orientation.

TL;DR: In this paper, the electronic properties of chemically modified armchair ribbons were investigated by means of density functional theory, and it was shown that edge substitutions at low density do not significantly alter the band gap, while bulk substitution promotes the onset of semiconducting-metal transitions.
