Journal ArticleDOI
Raman Spectroscopy of Graphene Edges
Cinzia Casiraghi,Achim Hartschuh,Huihong Qian,S. Piscanec,Carsten Georgi,A. Fasoli,K. S. Novoselov,Denis M. Basko,Andrea C. Ferrari +8 more
TL;DR: A detailed Raman investigation of graphene flakes with edges oriented at different crystallographic directions is presented and a real space theory for Raman scattering is developed to analyze the general case of disordered edges.
Journal ArticleDOI
Raman Spectroscopy of Graphene Edges
Cinzia Casiraghi,Achim Hartschuh,Huihong Qian,S. Piscanec,Carsten Georgi,K. S. Novoselov,Denis M. Basko,Andrea C. Ferrari +7 more
TL;DR: In this article, the position, width and intensity of G and D peaks at the edges are studied as a function of the incident light polarization, and the D-band is strongest for light polarized parallel to the edge and minimum for perpendicular orientation.
Journal ArticleDOI
Rayleigh Imaging of Graphene and Graphene Layers
Cinzia Casiraghi,Achim Hartschuh,Elefterios Lidorikis,Huihong Qian,Hayk Harutyunyan,Tobias Gokus,Kostya S. Novoselov,Andrea C. Ferrari +7 more
TL;DR: Rayleigh imaging is a general, simple, and quick tool to identify graphene layers, which is readily combined with Raman scattering, that provides structural identification.
Journal ArticleDOI
Electron and phonon renormalization near charged defects in carbon nanotubes.
I. O. Maciel,Neil Anderson,Neil Anderson,Marcos A. Pimenta,Achim Hartschuh,Huihong Qian,Mauricio Terrones,Humberto Terrones,Jessica Campos-Delgado,Apparao M. Rao,Lukas Novotny,Ado Jorio +11 more
TL;DR: The effects of a single defect on electrons and phonons in single-wall carbon nanotubes are characterized experimentally and the relation between atomic response and the readily accessible macroscopic behaviour is captured.
Journal ArticleDOI
Polyurea-functionalized multiwalled carbon nanotubes: synthesis, morphology, and Raman spectroscopy.
Chao Gao,Yizheng Jin,Hao Kong,Raymond L.D. Whitby,Steve F. A. Acquah,G Y Chen,Huihong Qian,Achim Hartschuh,S. R. P. Silva,Simon J. Henley,Peter K. Fearon,Harold W. Kroto,David R. M. Walton +12 more
TL;DR: Comparative experiments showed that the grafted polymer species and structures have a strong effect on the Raman signals of polymer-functionalized MWNTs, resulting in various linear or hyperbranched polycondensed polymers.
