ABSTRACT
Raman spectroscopy has been used for decades as a powerful tool for variety of materials properties [Cardona et al. (1979); Cardona (1982)]. Under Raman process one understands the inelastic scattering of light by molecular vibrations which results in generation of scattered light at new frequencies which are the combinations of the primary photon frequency and the vibrations [Cardona (1982)]. Today Raman spectroscopy became standard spectroscopic tool for characterization of materials.
