Journal ArticleDOI

Probing the Nature of Defects in Graphene by Raman Spectroscopy

Axel Eckmann, +7 more
- 09 Jul 2012 - 
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

Radio-frequency plasma functionalization of carbon nanotubes surface O2, NH3, and CF4 treatments

Alexandre Felten, +4 more
- 07 Oct 2005 - 
TL;DR: In this paper, the influence of various plasma conditions (power, type of gas, treatment time, pressure, position of the CNT sample inside the chamber) on the functionalization of the MWCNT surface was analyzed by x-ray photoelectron spectroscopy.
Journal ArticleDOI

Raman study on defective graphene: Effect of the excitation energy, type, and amount of defects

Axel Eckmann, +5 more
- 15 Jul 2013 - 
TL;DR: In this article, the Raman cross section of the crystal lattice after defect introduction per unit of damaged area, where x = D or D �, was observed to be 0.
Journal ArticleDOI

Gas Sensing with Au-Decorated Carbon Nanotubes

Zeila Zanolli, +5 more
- 13 May 2011 - 
TL;DR: The understanding of the sensing ability at the atomic level opens the way to design new gas sensors and to tune their selectivity by predicting the nature of the metal that is the most appropriate to detect specific molecular species.
Journal ArticleDOI

A simple method for graphene production based on exfoliation of graphite in water using 1-pyrenesulfonic acid sodium salt

Huafeng Yang, +11 more
- 01 Mar 2013 - 
TL;DR: In this paper, a chemical approach based on supra-molecular and non-covalent interactions between graphene and 1-pyrenesulfonic acid sodium salt (Py-1SO3) was used to obtain a stable dispersion of graphene by using only water as solvent.
