Journal ArticleDOI

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
Strong light-matter interactions in heterostructures of atomically thin films.
L. Britnell,Ricardo M. Ribeiro,Ricardo M. Ribeiro,Axel Eckmann,Rashid Jalil,Branson D. Belle,Artem Mishchenko,Yong-Jin Kim,Yong-Jin Kim,Roman V. Gorbachev,Thanasis Georgiou,Sergey V. Morozov,Alexander N. Grigorenko,Andre K. Geim,Cinzia Casiraghi,Cinzia Casiraghi,A. H. Castro Neto,K. S. Novoselov +17 more
TL;DR: Transition metal dichalcogenides sandwiched between two layers of graphene produce an enhanced photoresponse, which allows development of extremely efficient flexible photovoltaic devices with photoresponsivity above 0.1 ampere per watt (corresponding to an external quantum efficiency of above 30%).
Journal ArticleDOI
Probing the Nature of Defects in Graphene by Raman Spectroscopy
Axel Eckmann,Alexandre Felten,Alexandre Felten,Artem Mishchenko,L. Britnell,Ralph Krupke,Kostya S. Novoselov,Cinzia Casiraghi +7 more
TL;DR: A detailed analysis of the Raman spectra of graphene containing different type of defects is presented, finding that the intensity ratio of the D and D' peak is maximum for sp(3)-defects, it decreases for vacancy-like defects, and it reaches a minimum for boundaries in graphite.
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
Raman spectroscopy of hydrogenated amorphous carbons
TL;DR: In this paper, a comprehensive multiwavelength Raman investigation of a variety of hydrogenated amorphous carbons is presented, ranging from polymeric $a\text{\ensuremath{--}}\mathrm{-}:\mathrm {C} :Hs}$ to diamond-like $a \text{-}} \mathm{-\m{C}:\m{Hs}.
