Ultrafast Solvent-Assisted Sodium Ion Intercalation into Highly Crystalline Few-Layered Graphene.
TL;DR: It is demonstrated that a diglyme solvent shell encapsulating a sodium ion acts as a "nonstick" coating to facilitate rapid ion insertion into crystalline few-layer graphene and bypass slow desolvation kinetics.

Direct transfer of graphene onto flexible substrates
Luiz Gustavo Pimenta Martins,Yi Song,Tingying Zeng,Mildred S. Dresselhaus,Jing Kong,Paulo T. Araujo +5 more
TL;DR: In this paper, the authors explore the direct transfer via lamination of chemical vapor deposition graphene onto different flexible substrates, including polytetrafluoroethylene filter membranes, PVC, cellulose nitrate/cellulose acetate filter membrane, polycarbonate, paraffin, polyethylene terephthalate, paper, and cloth.

Electrical characteristics of multilayer MoS2 FET's with MoS2/graphene heterojunction contacts.
Joon Young Kwak,Jeonghyun Hwang,Brian Calderon,Hussain Alsalman,Nini Munoz,Brian Schutter,Michael G. Spencer +6 more
TL;DR: The electrical properties of multilayer MoS2/graphene heterojunction transistors are investigated and the charge transport mechanism in both junctions was determined to be either thermionic-field emission or field emission depending on bias voltage and temperature.

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
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.

Raman spectrum of graphene and graphene layers.
Andrea C. Ferrari,Jannik C. Meyer,Vittorio Scardaci,Cinzia Casiraghi,Michele Lazzeri,Francesco Mauri,S. Piscanec,Da Jiang,K. S. Novoselov,S. Roth,A. K. Geim +10 more
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.
