Disentanglement of the electronic properties of metallicity-selected single-walled carbon nanotubes

Abstract: The inherent structure of single-walled carbon nanotubes ͑SWCNTs͒ provides them tremendous value as archetypical one-dimensional ͑1D͒ solids, which exhibit van Hove singularities in their local density of states, Tomonaga-Luttinger liquid behavior, ballistic transport properties, and in many other aspects, features of 1D quantum systems, which allow the study of fundamental problems. Therefore, unraveling the signature of their peculiar electronic structure as pristine material is a prerequisite for tracing an… Show more

“…In any case, we find a good agreement regarding the fine structures, which have a long lifetime yielding sharp and distinct peaks on the XAS response perpendicular to the tube axis and on the other hand to the broad π * resonance along the tube axis having a strong lifetime broadening like in graphite. This is in good agreement with the two fold XAS response we observed in our previous experimental report [8] where we attributed this fine structure to the molecular like response of the vHs of the corresponding SWCNTs which are polarized perpendicular to the tube axis. The overall shape of the C1s π * peak shows close similarities to the π * resonance of bulk sp 2 carbon in graphite or graphene.…”

“…In Ref. [8] we proved, by using the metallicity sorted SWCNT with a mean diameter of 13.7Å, that this fine structure is related to the vHs of the individual SWCNTs. In that contribution we used diameter cumulative TB calculations of the electronic structure, and found a perfect match to the experimental spectra.…”

“…More recently, it has emerged as a particularly useful probe for low-dimensional carbon-based nanomaterials such as carbon fibers 1 , thin films 2 , nanotubes 3,4 , and graphene 5,6 . Measured binding energies are often compared to molecular reference values to identify the corresponding atomic structures.…”

“…20, 21 Ayala et al concluded that the interaction between different metallic SWCNTs within a bundle of only metallic SWCNTs is small enough to stabilize a TLL state. 22 The results of transport experiments in isolated and bundled SWCNTs can also be interpreted in terms of a TLL state, [23][24][25] although there remain difficulties in interpreting the role of the contacts. Thus, the effect of bundling on the one-dimensional electronic state in SWCNTs remains elusive.…”
