Abstract
Electronic properties of single-walled carbon nanotubes intercalated with lithium are investigated by NMR. NMR experiments reveal a metallic ground state for all of the following stoichiometries with , 7, and 6. A continuous increase of the density of states at the Fermi level according to the Li concentration is observed up to . From NMR, evidence of inequivalent Li sites is reported, corresponding to preferential sites of intercalation and binding between Li and C.
