Résumé:

We study the Raman spectra of Li-doped SWNT films. A monotonic upshift of the tangential modes, and a concomitant progressive loss of the resonant behavior of the Raman signal, are evidenced when the Li rate increases. No significant change is observed all over the temperature range 10-300K. (C) 2002 Elsevier Science B.V. All rights reserved.
