Abstract: Resonance Raman spectra of individual strained ultralong single-wall
carbon nanotubes (SWNTs) are studied. Torsional and uniaxial strains are intr
oduced by atomic force microscopy manipulation. Torsional strain strongly affe
cts the Raman spectra, inducing a large downshift in the E-2 symmetry mode in
the G(+) band, but a slight upshift for the rest of the G modes and also an up
shift in the radial breathing mode (RBM). Whereas uniaxial strain has no effec
t on the frequency of either the E-2 symmetry mode in the G(+) band or the RBM
, it downshifts the rest of the G modes. The Raman intensity change reflects t
he effect of these strains on the SWNT electronic band structure.
