Optical Anisotropy of Semiconducting Single-Wall Carbon Nanotubes

We measure the full optical anisotropy of individual semiconducting single-wall carbon nanotubes (SWNTs). Dispersion of aligned SWNTs in stretched polymer films is confirmed with small-angle scattering and near-infrared fluorescence spectroscopy. By combining absorption spectroscopy with transmission ellipsometry and polarization-dependent resonant Raman scattering, we obtain the first independent measures of the real and imaginary parts of the intrinsic SWNT permittivity, linked $a$ $posteriori$ through the Kramers-Kr\o}nig relations, for small-diameter semiconducting SWNTs.
