Electronic transport in single-walled nanotubes of known chiral indices

By measuring the Rayleigh scattering spectra of individual single-walled carbon nanotubes, we are able to measure the optical transition energies and therefore deduce the chiral indices (n,m).~ Using a simple mechanical transfer process, we can transfer the optically characterized tubes to a substrate.~ Following fabrication of metallic leads using e-beam lithography, the electrical transport properties of these tubes can be probed.~ We will present data on semiconducting, chiral metal and armchair metal SWNTs.
