Journal ArticleDOI
Separation of Metallic from Semiconducting Single-Walled Carbon Nanotubes
TL;DR: This work has developed a method to separate metallic from semiconducting single-walled carbon nanotubes from suspension using alternating current dielectrophoresis, taking advantage of the difference of the relative dielectric constants of the two species with respect to the solvent.
Journal ArticleDOI
Wideband-tuneable, nanotube mode-locked, fibre laser
Fengqiu Wang,Aleksey Rozhin,Vittorio Scardaci,Zhipei Sun,Frank Hennrich,Ian H. White,William I. Milne,Andrea C. Ferrari +7 more
TL;DR: In principle, different diameters and chiralities of nanotubes could be combined to enable compact, mode-locked fibre lasers that are tuneable over a much broader range of wavelengths than other systems.
Journal ArticleDOI
Sidewall Functionalization of Carbon Nanotubes This work was supported by the European Union under the 5th Framework Research Training Network 1999, HPRNT 1999-00011 FUNCARS.
Michael Holzinger,Otto Vostrowsky,Andreas Hirsch,Frank Hennrich,Manfred M. Kappes,Robert Weiss,Frank Jellen +6 more
TL;DR: The addition of nitrenes, nucleophilic carbenes, and radicals affords soluble, individual single-walled nanotubes by covalent sidewall functionalization, a fundamental problem in nanotube chemistry.
Journal ArticleDOI
Functionalization of single-walled carbon nanotubes with (R-)oxycarbonyl nitrenes.
Michael Holzinger,Juergen Abraham,Paul Whelan,Ralf Graupner,Lothar Ley,Frank Hennrich,Manfred M. Kappes,Andreas Hirsch +7 more
TL;DR: The use of Raman and electron absorption spectroscopy showed that the electronic properties of the SWCNTs are mostly retained after functionalization, indicating a low degree of addition within this series of SWC NT derivatives.
Journal ArticleDOI
Chirality distribution and transition energies of carbon nanotubes
TL;DR: From resonant Raman scattering on isolated nanotubes, the optical transition energies, the radial breathing mode frequency, and the Raman intensity of both metallic and semiconducting tubes are obtained.
