Structural anisotropy of magnetically aligned single wall carbon nanotube films
نویسندگان
چکیده
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 mm) measured by x-ray diffraction is slightly broader, 3563°. Aligned films are denser than ordinary filter-deposited ones, and much denser than as-grown material. Optimization of the process is expected to yield smaller FWHMs and higher densities. © 2000 American Institute of Physics. @S0003-6951~00!05131-7#

Electrical 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 کاملMagnetically 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 کاملAnisotropy in the X-ray absorption of vertically aligned single wall carbon nanotubes
Carbon nanotubes are archetypical one dimensional systems, with peculiar anisotropic electronic properties. Only recently μm thick films of vertically aligned SWNT became available. The vertical alignment of the nanotube mats allows the realization of scattering geometries promoting specific dipole transitions parallel and normal to the axis of the SWNT. We find well expressed mosaic spreads fo...
متن کاملDielectric response of aligned semiconducting single-wall nanotubes.
We report measurements of the full intrinsic optical anisotropy of isolated single-wall carbon nanotubes (SWNTs). By combining absorption spectroscopy with transmission ellipsometry and polarization-dependent resonant Raman scattering, we obtain the real and imaginary parts of the SWNT permittivity from aligned semiconducting SWNTs dispersed in stretched polymer films. Our results are in agreem...
متن کاملDirect measurement of the polarized optical absorption cross section of single-wall carbon nanotubes.
We determine optical absorption cross sections of single-wall carbon nanotubes for visible light copolarized and cross polarized with respect to the nanotube axis. The need for perfectly aligned ensembles in absorbance measurements is eliminated by using Raman scattering to measure the nematic order parameter in magnetically aligned nanotube suspensions. The absorbance data allow the first quan...
