Non-Dendritic Zn Electrodeposition Enabled by Zincophilic Graphene Substrates.
Tara Foroozan,Vitaliy Yurkiv,Soroosh Sharifi-Asl,Ramin Rojaee,Farzad Mashayek,Reza Shahbazian-Yassar +5 more
TL;DR: It is shown that cycling performance of Zn metal anode can be improved significantly by utilizing monolayer graphene (Gr) as the electrodeposition substrate, and that electrodeposited Zn on Gr substrate has a compact, uniform and non-dendritic character.

Raman scattering study of the phonon dispersion in twisted bilayer graphene
TL;DR: In this paper, a superlattice-induced Raman scattering can be used to probe the phonon dispersion in twisted bilayer graphene (tBLG), and the effect reported in this paper is different from the widely studied double-resonance in graphene-related materials in many aspects.

Graphene enhanced flexible expanded graphite film with high electric, thermal conductivities and EMI shielding at low content
TL;DR: In this paper, a small amount of flexible graphene (GE) is introduced to endow expanded graphite (EG) films with good flexibility and mechanical properties by forming simulate shell structure, and the influence of oxidation degree and sheet thickness for carbon sheets as well as the lateral size of GE on the film performance is carefully discussed.

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.

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.
