Abstract
Resonant Raman scattering (RRS) measurements made with a tunable laser prov ide a highly reliable technique to study the shape;of the joint density of electronic states (JDOS) of isolated single-wall carbon nanotubes (SWNTs). RRS can be used to determine the energy value for the one-dimensional (1D) van Hove singularities of a SWNT with a precision better than 5 meV, thereb y providing important information that could be used for subsequent measure ments on this same SWNT. With RRS, the measured width of the JDOS is on the order of similar to0.1-1.0 meV, further demonstrating that SWNTs really pr ovide a remarkably good model for 1D mesoscopic systems.
