Mechanical properties of graphene
Y. W. Sun,Dimitrios G. Papageorgiou,Colin J. Humphreys,David J. Dunstan,Pascal Puech,John E. Proctor,Colin Bousige,Denis Machon,Alfonso San-Miguel +8 more
TL;DR: In this article, the authors present a review of the mechanical properties of graphene with particular attention to what is established and what is still uncertain, concluding that the best values for bending stiffness come from graphite, when available.

Hierarchical graphene nanoribbon assemblies feature unique electronic and mechanical properties.
Zhi Ping Xu,Markus J. Buehler +1 more
TL;DR: It is found that the energy gap of the bulk material shrinks as the width of the constituting graphene nanoribbons increases, enabling the synthesis of a broader class of biomimetic multifunctional mechanomutable and electromutable nanomaterials for electromechanical applications.
Journal ArticleDOI
Bipolar Exfoliation and in Situ Deposition of High-Quality Graphene for Supercapacitor Application
TL;DR: In this paper, bipolar electrochemistry concept is utilized to design a single-step and controllable process for simultaneously exfoliating a graphite source and depositing both graphene oxide and reduced graphene oxide layers on conductive substrates.

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.
Journal ArticleDOI
Experimental observation of the quantum Hall effect and Berry's phase in graphene
TL;DR: In this paper, an experimental investigation of magneto-transport in a high-mobility single layer of Graphene is presented, where an unusual half-integer quantum Hall effect for both electron and hole carriers in graphene is observed.
