Journal ArticleDOI
Carbon onions as nanoscopic pressure cells for diamond formation
Florian Banhart,P. M. Ajayan +1 more
TL;DR: In this article, it was shown that carbon onion cores can be transformed to diamond by electron irradiation of graphitic carbon materials, and that the carbon onions act as nanoscopic pressure cells for diamond formation.
Journal ArticleDOI
Electronic structure and localized states at carbon nanotube tips
David L. Carroll,Philipp Redlich,P. M. Ajayan,Jean-Christophe Charlier,Xavier Blase,A. De Vita,Roberto Car +6 more
TL;DR: In this article, topology related changes in the local density of states near the ends of closed carbon nanotubes are investigated using spatially resolved scanning tunneling spectroscopy and tight binding calculations.
Journal ArticleDOI
BCN nanotubes and boron doping of carbon nanotubes
TL;DR: In this paper, the synthesis of carbon nanotubes and boron doped (1 to 5 at.% B) was achieved by an electric arc-discharge between an anode made of homogeneous BC 4 N and a cathode making of graphite.
Journal ArticleDOI
The formation, annealing and self-compression of carbon onions under electron irradiation
TL;DR: In this article, electron irradiation-induced basal plane disordering in single and multi-shell carbon nanotubes and onions is found to be inhibited at irradiation temperatures above 300°C.
Journal ArticleDOI
Zipper mechanism of nanotube fusion: theory and experiment.
Mina Yoon,Seungwu Han,Gunn Kim,Sang Bong Lee,Savas Berber,Eiji Osawa,Jisoon Ihm,Mauricio Terrones,Florian Banhart,Jean-Christophe Charlier,Nicole Grobert,Humberto Terrones,P. M. Ajayan,David Tománek +13 more
TL;DR: A new microscopic mechanism to explain the unusually fast fusion process of carbon nanotubes, involving only Stone-Wales bond rearrangements with low activation barriers, is proposed.
