Localized and delocalized charge transport in single-wall carbon-nanotube mats

Localized and delocalized charge transport in single-wall carbon-nanotube mats

We measured the complex dielectric constant in mats of single-wall carbon nanotubes between 2.7 K and 300 K up to 0.5 THz. The data are well understood in a Drude approach with a negligible temperature dependence of the plasma frequency ${\ensuremath{\omega}}_{p}$ and scattering time $\ensuremath{\tau}$ with an additional contribution of …
