Raman crystallinity

WebbRaman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions. It is based upon the interaction of light with the chemical bonds within a material. Raman is a light scattering technique, whereby a molecule scatters ... WebbRaman spectroscopy can provide information on the local structure and crystallinity of Bi nanoparticles and thin films [10,27,28,29,30,31]. In this work, we have analyzed film thickness-induced spectral changes for β -Bi and α -Bi samples.
