Abstract

X-ray absorption (resonant) photoelectron spectroscopy has been employed to investigate electronic structure of Eu atomic wires encapsulated in single-wall carbon nanotubes (SWCNTs). The measurements reveal that there is a substantial electron transfer of +1.79 ± 0.11 from a Eu atom to the surrounding SWCNT. The shape of the observed Fermi edge is different from that of a three-dimensional metal, suggesting that electrons in this one-dimensional system form a Tomonaga-Luttinger liquid.
