Abstract
A review of the resonance Raman effect in one-dimensional (1D) system is
presented. Due to the strong electron-phonon coupling and the quantum
confinement of electrons and phonons in 1D systems. interesting effects
are observed, Such as asymmetries in the Stokes/anti-Stokes spectra and
line-shape dependence on satisfying the resonance condition. Analysis of
these effects give detailed information about the confined phonon and
electron states. showing that resonance inicro-Raman spectroscopy of
phonon modes can determine electronic and structural properties of
1D-systems. The single wall carbon nanotube (SWNT) is used as a
prototype 1D system for describing resonance Raman scattering in 1D,
since many experimental results are now available for this system at the
single nanotube level, and because detailed theoretical modeling can be
carried out for this system. The results on SWNTs, should provide a
valuable guide for Raman studies on other 1D systems. It is also shown
that the resonance Raman effect provides a useful technique for
obtaining phonon dispersion relations for nanoscale samples, and that
measurements on low dimensional systems can be used to obtain important
information about related higher dimensional systems that is otherwise
difficult to obtain.
