Journal ArticleDOI
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.
Journal ArticleDOI
The structure of suspended graphene sheets
Jannik C. Meyer,A. K. Geim,Mikhail I. Katsnelson,Kostya S. Novoselov,Timothy J. Booth,S. Roth +5 more
TL;DR: These studies by transmission electron microscopy reveal that individual graphene sheets freely suspended on a microfabricated scaffold in vacuum or air are not perfectly flat: they exhibit intrinsic microscopic roughening such that the surface normal varies by several degrees and out-of-plane deformations reach 1 nm.
Journal ArticleDOI
Graphene at the edge: stability and dynamics.

Crommie,Marvin L. Cohen,Marvin L. Cohen,Marvin L. Cohen,Steven G. Louie,Steven G. Louie,Steven G. Louie,Alex Zettl,Alex Zettl,Alex Zettl +32 more
TL;DR: This study of an ideal low-dimensional interface, a hole in graphene, exhibits the complex behavior of atoms at a boundary with the mechanism of edge reconstruction investigated and the stability of the “zigzag” edge configuration demonstrated.
Journal ArticleDOI
Direct Imaging of Lattice Atoms and Topological Defects in Graphene Membranes
Jannik C. Meyer,Christian Kisielowski,Rolf Erni,Marta D. Rossell,Michael F. Crommie,Alex Zettl +5 more
TL;DR: Multiple five- and seven-membered rings appear exclusively in combinations that avoid dislocations and disclinations, in contrast to previous observations on highly curved (tube- or fullerene-like) graphene surfaces.
Journal ArticleDOI
Atomic Structure of Reduced Graphene Oxide
Cristina Gómez-Navarro,Jannik C. Meyer,R. S. Sundaram,Andrey Chuvilin,Simon Kurasch,Marko Burghard,Klaus Kern,Klaus Kern,Ute Kaiser +8 more
TL;DR: The layers are found to comprise defect-free graphene areas with sizes of a few nanometers interspersed with defect areas dominated by clustered pentagons and heptagons, which makes all carbon atoms in these defective areas undetectable by spectroscopic techniques.
