Abstract

For the correct interpretation of Raman spectra it is important to realize that the scattering process in carbon nanotubes is doubly resonant, a feature which - although known from semiconductors - is greatly enhanced by the peculiar bandstructure of graphene near the K-point. We discuss the double-resonant process and, as examples of its importance, show how the relative defect concentration in a set of boron-doped multiwalled tubes can be measured and how the determination of the diameter through the radial breathing mode (RBM) is affected by double resonance.
