Channeling of charge carrier plasmons in carbon nanotubes
Ab initio calculations of the loss-function of potassium intercalated and electron loaded bundles of single walled carbon nanotubes yield a channeled charge carrier plasmon, without perpendicular dispersion. Experimentally, we probe the momentum dependent loss-function of sparse arrays of potassium intercalated single walled carbon nanotubes by angle resolved electron energy loss spectroscopy and confirm this intrinsic channeling. The charge carrier plasmon energy is via in-situ intercalation tunable in the near visible infrared energy range from 0.85 eV to 1.15 eV.
