The scattering intensity (SI) for an electron resonant Raman scattering (ERRS) process in a free-standing semiconductor quantum wire of cylindrical geometry associated with bulk longitudinal optical (LO) phonon modes or the surface optical (SO) phonon modes is calculated for T=0 K . The Fröhlich interaction is considered to illustrate the theory for a GaAs system. Electron states are confined within a free-standing quantum wire (FSW). Single parabolic conduction and valence bands are assumed. The selection rules are studied. Numerical results and a discussion are also presented for various radii of the cylindrical quantum wires.

Polarized Raman

Resonant Raman scattering of degenerate interacting two-channel quantum wire is studied. All collective excitations of two-channel quantum wire are shown to give rise to peaks in the polarized Raman spectra near resonance. If there exist certain symmetries among interactions, a resonant peak can also appear in the depolarized Raman spectra, in contrast to the single-channel case studied by Sassetti and Kramer. We also calculate the explicit form of the scattering cross-section away from the peaks. The above features may be experimentally verified in armchair carbon nanotube systems.
