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."

(SPRINGER/PLENUM PUBLISHERS, 1998-08-01)We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the ...
