Chirality changes in carbon nanotubes studied with near-field Raman spectroscopy

N Anderson, A Hartschuh, L Novotny - Nano letters, 2007 - ACS Publications
We report on the direct visualization of chirality changes in carbon nanotubes by mapping
local changes in resonant RBM phonon frequencies with an optical resolution of 40 nm
using near-field Raman spectroscopy. We observe the transition from semiconducting-to …
