Abstract
Although the Raman effect was discovered nearly 80 years ago, it is only
recently that the special characteristics of Raman scattering for
one-dimensional systems have been seriously considered. This review
focuses on the special interest of the Raman effect for one-dimensional
systems that is of particular relevance to carbon nanostructures. Two
examples of Raman scattering in one-dimensional systems are given. The
first illustrates the use of Raman spectroscopy to reveal the remarkable
structure and properties of carbon nanotubes arising from their
one-dimensionality. Some of the recent advances in using Raman
spectroscopy to study doping and intercalation to modify nanotube
properties are reviewed, in the context of a one-dimensional system. The
second example is the Raman spectra of a linear chain of carbon atoms
and the special properties of this interesting system. New approaches
toward applying Raman spectroscopy to carbon nanostructures are also
emphasized. (c) 2006 Published by Elsevier B.V.
