Raman characterization of ABA- and ABC-stacked trilayer graphene
Chunxiao Cong,Ting Yu,Ting Yu,Kentaro Sato,Jingzhi Shang,Riichiro Saito,Gene Dresselhaus,Mildred S. Dresselhaus +7 more
TL;DR: A systematic experimental and theoretical analysis of the Raman modes in bothBernal (ABA stacking order) and rhombohedral trilayer graphene (3LG) shows that the G band, G' (2D) band, and the intermediate-frequency combination modes of 3LGs are sensitive to the stacking order of 3LG.

Raman spectroscopy as a tool for the analysis of carbon-based materials (highly oriented pyrolitic graphite, multilayer graphene and multiwall carbon nanotubes) and of some of their elastomeric composites
TL;DR: In this paper, the effects of the laser heating and the double resonance Raman scattering are investigated as a prerequisite for a correct interpretation of the Raman spectra of carbon materials-based composites.

Graphene oxide strongly inhibits amyloid beta fibrillation
Morteza Mahmoudi,Omid Akhavan,Mahdi Ghavami,Farhad Rezaee,Farhad Rezaee,Seyyed Mohammad Amin Ghiasi +5 more
TL;DR: It is shown that GO and their protein-covered surfaces delay the AβF process via adsorption of amyloid monomers and the large available surface of GO sheets candelay the A βF process by adsorbed monomers.

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.

Two-dimensional gas of massless Dirac fermions in graphene
Kostya S. Novoselov,A. K. Geim,Sergey V. Morozov,Da Jiang,Mikhail I. Katsnelson,Irina V. Grigorieva,S. V. Dubonos,A. A. Firsov +7 more
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.
