Abstract

We perform tunable resonant Raman scattering on 17 semiconducting and seven metallic singly resonant single wall carbon nanotubes. The measured scattering cross section as a function of laser energy provides information about a tube's electronic structure, the lifetime of intermediate states involved in the scattering process, and also the energies of zone center optical phonons. Recording the scattered Raman signal as a function of tube location in the microscope focal plane allows us to construct two-dimensional spatial maps of singly resonant tubes. We also describe a spectral nano-scale artifact, which we have termed as the "nano-slit effect."
