Peter Blake,P. D. Brimicombe,Rahul R. Nair,Timothy J. Booth,Da Jiang,Fred Schedin,Leonid Ponomarenko,Sergey V. Morozov,Helen F. Gleeson,Ernie W. Hill,Andre K. Geim,Kostya S. Novoselov +11 more
TL;DR: This letter demonstrates liquid crystal devices with electrodes made of graphene that show excellent performance with a high contrast ratio and discusses the advantages of graphene compared to conventionally used metal oxides in terms of low resistivity, high transparency and chemical stability.
Journal ArticleDOI
Light-emitting diodes by band-structure engineering in van der Waals heterostructures
Freddie Withers,O. Del Pozo-Zamudio,Artem Mishchenko,A. P. Rooney,Ali Gholinia,Kenji Watanabe,T. Taniguchi,Sarah J. Haigh,Andre K. Geim,Alexander I. Tartakovskii,Kostya S. Novoselov +10 more
TL;DR: In this paper, the authors describe light-emitting diodes (LEDs) made by stacking metallic graphene, insulating hexagonal boron nitride and various semiconducting monolayers into complex but carefully designed sequences.
Journal ArticleDOI
Tunable sieving of ions using graphene oxide membranes
Jijo Abraham,K. S. Vasu,Christopher D. Williams,Kalon Gopinadhan,Yang Su,C. T. Cherian,James Dix,Eric Prestat,Sarah J. Haigh,Irina V. Grigorieva,Paola Carbone,Andre K. Geim,Rahul R. Nair +12 more
TL;DR: A simple scalable method is demonstrated to obtain graphene-based membranes with limited swelling, which exhibit 97% rejection for NaCl and decrease exponentially with decreasing sieve size, but water transport is weakly affected.
Journal ArticleDOI
Breakdown of the adiabatic Born-Oppenheimer approximation in graphene.
Simone Pisana,Michele Lazzeri,Cinzia Casiraghi,Kostya S. Novoselov,Andre K. Geim,Andrea C. Ferrari,Francesco Mauri +6 more
TL;DR: It is shown that ABO fails in graphene, a zero-bandgap semiconductor that becomes a metal if the Fermi energy is tuned applying a gate voltage, Vg, which induces a stiffening of the Raman G peak that cannot be described within ABO.
Journal ArticleDOI
Microfabricated adhesive mimicking gecko foot-hair.
Andre K. Geim,S. V. Dubonos,Irina V. Grigorieva,Kostya S. Novoselov,Andrey A. Zhukov,S. Yu. Shapoval +5 more
TL;DR: A prototype of such 'gecko tape' is reported on, made by microfabrication of dense arrays of flexible plastic pillars, the geometry of which is optimized to ensure their collective adhesion.
