Resonance Raman study of I2-intercalated single-walled carbon nanotubes

Abstract

We conducted resonance Raman studies on the iodine-intercalated bundles of single-walled carbon nanotubes (SWNTs). The Raman spectra obtained using the 647.1-nm line of a Kr-ion laser indicate that I2 intercalation affects the electronic state of SWNTs, particularly the metallic ones. The effect of I2 intercalation is thermally reversible. © 2007 IEEE.
