Résumé: In order to decide definitely on the dependence of the intensity of the Breit-Wigner-Fano (BWF) component with the size of the bundle, we have measured the radial breathing modes and tangential modes (TMs) of well defined metallic individual single-wall carbon nanotubes (SWCNTs) and individual SWCNT bundles. In this aim, a complete procedure including the preparation of the substrates, the sample preparation, atomic-force-microscopy imaging and Raman spectroscopy has been developed. From this procedure, we show unambiguously that the BWF component vanishes in isolated metallic SWCNTs. In other words, the observation of a BWF component in the TM bunch is an intrinsic feature of the metallic SWCNT bundle.

Résumé: We have developed a versatile catalyst-assisted chemical vapor deposition (CVD) technique for the synthesis of single-walled carbon nanotubes (SVNTs) from discrete nickel nanoparticles (average diameter of 4.7 +/- 1.4 nm). Atomic force microscopy (AFM), transmission electron microscopy (TEM) and micro-Raman spectroscopy are used to characterize these as-grown nanotubes. Using a conventional set-up, we are able to produce isolated SWNTs with a narrow diameter distribution (1.5 +/- 0.5 nm). The advantages of such a versatile CVD method for the study of physical properties at the single nanotube level are illustrated by means of two prospective studies on vibrational and electrostatic properties of SWNTs.

Résumé: Discrete nickel catalyst nanoparticles (NP) have been used to grow isolated single-walled carbon nanotubes by chemical vapor deposition (CVD). Atomic force microscopy (AFM), transmission electron microscopy (TEM) and micro-Raman spectroscopy are used to characterize these as-grown, isolated nanotubes. Using a conventional setup, we are able to produce narrow diameter distribution single-walled carbon nanotubes (SWNTs) (1.45 +/- 0.5 nm), showing a clear mismatch with the larger broad size distribution of the catalyst nanoparticles (4.7 +/- 1.5 nm). Investigation of the growth conditions allowed us to synthesize, starting with the same catalyst materials, various carbon nanotube (CNT) samples with a wide range of characteristics. The advantages of such a versatile CVD method for the study of physical properties at the single nanotube level are illustrated by means of two prospective studies on SWNTs mechanical and vibrational properties.
