Magnetically aligned single wall carbon nanotube films: preferred orientation and anisotropic transport properties
Thick films of single wall carbon nanotubes ~SWNT! exhibiting in-plane preferred orientation have been produced by filter deposition from suspension in strong magnetic fields. We characterize the field-induced alignment with x-ray fiber diagrams and polarized Raman scattering, using a model which includes a completely unaligned fraction. We correlate the texture parameters with resistivity and ...
متن کاملElectrical and thermal transport properties of magnetically aligned single wall carbon nanotube films
Dense, thick films of aligned single wall carbon nanotubes and nanotube ropes have been produced by filtration/deposition from suspension in strong magnetic fields. Electrical resistivity exhibits moderate anisotropy with respect to the alignment axis, while the thermopower is the same when measured parallel or perpendicular to this axis. Both parameters have identical temperature dependencies ...
متن کاملStructural anisotropy of magnetically aligned single wall carbon nanotube films
Thick films of aligned single wall carbon nanotubes and ropes have been produced by filtration/ deposition from suspension in strong magnetic fields. We measured mosaic distributions of rope orientations in the film plane, for samples of different thicknesses. For an ;1 mm film the full width at half maximum ~FWHM! derived from electron diffraction is 25° – 28°. The FWHM of a thicker film (;7 m...
متن کاملSingle Wall Carbon Nanotube Fibers Extruded from Super-Acid Suspensions: Preferred Orientation, Electrical and Thermal Transport
Fibers of single wall carbon nanotubes extruded from super-acid suspensions exhibit preferred orientation along their axes. We characterize the alignment by x-ray fiber diagrams and polarized Raman scattering, using a model which allows for a completely unaligned fraction. This fraction ranges from 0.17 to 0.0560.02 for three fibers extruded under different conditions, with corresponding Gaussi...
