Fullerene single-wall nanotubes (SWNTs) were produced in yields of more than 70 percent by condensation of a laser-vaporized carbon-nickel-cobalt mixture at 1200°C. X-ray diffraction and electron microscopy showed that these SWNTs are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms. The x-ray form factor is consistent with that of uniformly charged cylinders 13… 
Conductivity enhancement in single-walled carbon nanotube bundles doped with K and Br
Single-walled carbon nanotubes (SWNTs), prepared by metal-catalysed laser ablation of graphite, form close-packed bundles or ‘ropes;. These rope crystallites exhibit metallic behaviour above 50K
Growth of single-wall carbon nanotubes within an ordered array of nanosize silica spheres
Single-wall carbon nanotubes (SWCNTs), which were well-separated individuals or, small bundles of two to five tubes, were produced in a controllable manner by disproportionation of CO at 700 °C and 1

Characteristics and Applications of Carbon Nanotubes with Different Numbers of Walls
Abstract Carbon nanotubes (CNTs) are quasi-one-dimensional (1D) tubular forms of sp2 carbon networks. They may contain one to several tens of concentric graphitic shells and are typically 1–50 nm in

Defects in Carbon Nanostructures
TLDR
The structures of the carbon nanotubes and particles were characterized here by bulk physical and chemical property measurements and indicate that they are highly defective and have a local structure similar to turbostratic graphite.

TLDR
The ordered condensed phase of carbon nanotubes is examined, finding that as the tube diameter varies, the structural properties show a clear transition between two regimes with qualitatively different behavior.

TLDR
Field emission of electrons from individually mounted carbon nanotubes has been found to be dramatically enhanced when the nanotube tips are opened by laser evaporation or oxidative etching, in a process that resembles unraveling the sleeve of a sweater.
X-ray powder diffraction from carbon nanotubes and nanoparticles.
TLDR
Detailed x-ray powder-diffraction measurements on a sample consisting of carbon nanotubes and nanoparticles demonstrate the existence of short-range interlayer stacking correlations, and calculations show that such correlations should not be observable in idealized models of nanot tubes.
