Diego L. Silva,João Luiz Elias Campos,Thales F. D. Fernandes,Jerônimo Nunes Rocha,Lucas R.P. Machado,Eder M. Soares,Douglas R. Miquita,Hudson Miranda,Cassiano Rabelo,Omar P. Vilela Neto,Ado Jorio,Luiz Gustavo Cançado +11 more
TL;DR: In this article, a metrological framework for statistical analysis of number of layers and stacking order in mass-produced graphene using Raman spectroscopy is presented, based on two complementary protocols, denominated by 2D and G. The 2D-protocol is based on the parameterized principal component analysis of the 2D band, and it measures interlayer coupling.

Mechanism of Oxygen Reduction in Aprotic Li–Air Batteries: The Role of Carbon Electrode Surface Structure
TL;DR: In this paper, the effects of imperfections in the planar sp2 surface structure of carbon on the Li oxygen reduction reaction (Li-ORR) mechanism by means of different model carbon electrodes (highly oriented pyrolytic graphite (HOPG), glassy carbon, basal, and edge planes of pyrotechnic graphite), in dimethyl sulfoxide (DMSO)-based electrolyte.

Enhanced thermal conductivity of graphene/polyimide hybrid film via a novel “molecular welding” strategy
TL;DR: In this article, a molecular welding strategy was realized for the fabrication of flexible, ultrathin, but highly conductive graphitized-graphene/polyimide (g-GO/PI) hybrid films.

Size-dependence of Raman scattering from graphene quantum dots: Interplay between shape and thickness
Sung Kim,Dong Hee Shin,Chang Oh Kim,Soo Seok Kang,Soong Sin Joo,Suk-Ho Choi,Sung Won Hwang,Cheolsoo Sone +7 more
TL;DR: In this article, the authors studied the Raman-scattering behavior of GQDs and found that the peak frequencies of D and 2D bands are almost irrespective of d, and the intensity of the D band is larger than that of the G band over almost full range of d.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.

The electronic properties of graphene
TL;DR: In this paper, the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations, are discussed.

Two-dimensional gas of massless Dirac fermions in graphene

TL;DR: This study reports an experimental study of a condensed-matter system (graphene, a single atomic layer of carbon) in which electron transport is essentially governed by Dirac's (relativistic) equation and reveals a variety of unusual phenomena that are characteristic of two-dimensional Dirac fermions.

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.

Interpretation of Raman spectra of disordered and amorphous carbon
Andrea C. Ferrari,John Robertson +1 more
TL;DR: In this paper, a model and theoretical understanding of the Raman spectra in disordered and amorphous carbon is given, and the nature of the G and D vibration modes in graphite is analyzed in terms of the resonant excitation of \ensuremath{\pi} states and the long-range polarizability of the long range bonding.
