Graphical Abstract
  • , atomic-scale wires comprised of sp-hybridized carbon atoms represent ideal 1D systems to potentially downscale devices to the atomic level. Carbon-atom wires (CAWs) can be arranged in two possible structures: a sequence of double bonds (cumulenes), resulting in a 1D metal, or an alternating sequence of
  • electronic structure from alternating to equalized bonds. Keywords: carbon nanostructures; cumulenes; polyynes; Raman spectroscopy; sp-hybridized carbon systems; Review Introduction Over the last decades carbon nanostructures have been widely investigated for their unique properties and for their potential
  • issues since the 1D atomic equalized structures tend to change into the alternating triple–single bond structures to reach a minimum energy configuration (i.e., due to the onset of a Peierls distortion). Such structural change has a direct effect on the electronic properties. Infinite cumulenes have one
