Journal ArticleDOI
Two-dimensional atomic crystals
Kostya S. Novoselov,Da Jiang,Fred Schedin,Timothy J. Booth,V. V. Khotkevich,Sergey V. Morozov,Andre K. Geim +6 more
TL;DR: By using micromechanical cleavage, a variety of 2D crystals including single layers of boron nitride, graphite, several dichalcogenides, and complex oxides are prepared and studied.
Journal ArticleDOI
Fine Structure Constant Defines Visual Transparency of Graphene
Rahul R. Nair,Peter Blake,Peter Blake,Alexander N. Grigorenko,K. S. Novoselov,Timothy J. Booth,Timothy J. Booth,Tobias Stauber,Tobias Stauber,Nuno M. R. Peres,Nuno M. R. Peres,A. K. Geim +11 more
TL;DR: It is shown that the opacity of suspended graphene is defined solely by the fine structure constant, a = e2/hc � 1/137 (where c is the speed of light), the parameter that describes coupling between light and relativistic electrons and that is traditionally associated with quantum electrodynamics rather than materials science.
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
Making graphene visible
Peter Blake,Ernie W. Hill,A. H. Castro Neto,K. S. Novoselov,Da Jiang,R. Yang,Timothy J. Booth,A. K. Geim +7 more
TL;DR: In this article, the authors study the visibility of graphene and show that it depends strongly on both thickness of SiO2 and light wavelength, and they find that ≈100nm is the most suitable wavelength for its visual detection.

Making graphene visible
Peter Blake,K. S. Novoselov,A. H. Castro Neto,Da Jiang,R. Yang,Timothy J. Booth,A. K. Geim,Ernie W. Hill +7 more
TL;DR: In this paper, the authors studied the visibility of graphene and showed that it depends strongly on both thickness of silicon dioxide and light wavelength, and they used a Fresnel-law-based model to quantitatively describe the experimental data without any fitting parameters.
