摘要
The progress on separation of single-walled carbon nanotubes according to their metallic character has allowed to access the unique electronic and optical properties long ago predicted. Whether the inevitable interactions of nanotubes in a bundle or single doping defects are in scope, the energies of charge carriers and lattice vibrations are modified. Based on this, we have made use of photoemission spectroscopy effectively to identify modifications of the underlying basic correlation effects in the electronic structure. Subsequently, we have deepened into the study of the valence band metallicity sorted samples and we have recorded, depending on the actual type of interaction within a film of bundles of purely metallic single wall carbon nanotube bundles, a compelling evidence for both a 1D Tomonaga-Luttinger power law scaling and a 3D Fermi liquid.
