“…Typically, TIS with the angular momentum l P 6 are separated 10-50 nm away from the surface, and their energies are a few meV below the vacuum level. In recent experiments [6], TIS with low l < 3 were observed to form in the vicinity of suspended nanotubes. Their lifetimes are about one order of magnitude longer than image states above flat metallic surfaces, in agreement with our expectations.…”

“…Initially, the sample is perturbed by the IR pump beam with a photon energy of 1.57 eV, which promotes the electron population from below E F into the conduction band. The resulting charge distribution, consisting of e-h pairs, is then probed with a UV pulse that energetically exceeds the sample work function of 4:24 0:05 eV by 0.47 eV [17]. In this configuration, energy dependent lifetimes of both the conduction electrons and the valence holes can be investigated [18].…”

The nature of low-energy excitations in multiwalled nanotubes (MWNTs) is investigated by means of two-color time-resolved photoemission. A careful analysis of the ballistic transport, secondary excitations, and band structure effects was employed in order to extract single electron lifetimes from the observed relaxation trend. It is demonstrated that in the vicinity of the Fermi level the energy dependence of e-e scattering times is inversely proportional to approximately the square of the excitation energy. This result provides strong evidence that electron transport in MWNTs exhibits a Fermi-liquid behavior, indicating that long-range e-e interaction along the tube vanishes due to screening.

“…We have suggested that extended states could also form above metallic CNT [144,145], when electrons spin around their mirror images in the CNTs. Recently, these "tubular image states" with long lifetimes were observed in photo-excitation experiments [146]. Here, we show that extended electronic states formed above metal-doped carbon nanostructures can be controlled by using external electric field [66].…”
