Carbon: The Material and itsCharacterization by Raman Spectroscopy

摘要

A brief review of the different aspects of carbon will be presented to demonstrate howthe physics associated with this material is full of surprises even though it is probably one of theoldest materials known to human civilization. An understanding of the properties of differentforms of carbon starting from its commonly known forms to some of its well established stableforms, such as graphite and diamond, and to those of more recent origin, namely the Fullerenes,Carbon Nanotubes, and the Graphene has drawn considerable attention of scientists at thepresent time. Attempts will be made to high light some of these feature. One of the establishedmethods of characterizing any form of carbon is to take recourse to Raman spectroscopy. With abrief and qualitative outline of the principles of Raman scattering, the Raman data on differentforms of carbon will be discussed to demonstrate some of the puzzling aspects of the material.
