| Popis: | Raman spectroscopy technique is potentially utilized to identify the chemical bonding in molecules or solids and doping in semiconducting materials. Even different forms of carbon materials could also be identified by this technique. Raman Spectroscopy helps in determining the size and conductivity of nanoscale system with high precision. The contents of this chapter include as follows: Sect. 11.2 describes the sample preparation method and instrumentation of confocal scanning microscopy which deals with the recording of Raman spectra of individual nanostructures. Section 11.3 discusses the geometrical structure, electronic band structure, phonon properties, and Raman spectra of single-walled carbon nanotubes (SWNTs). The Raman scattering of multi-walled carbon nanotubes (MWNTs) has also been discussed in Sect. 11.3. Section 11.3 presents the discussion on phonon properties and Raman scattering of graphene. In Sect. 11.5, the basic mechanism of surface-enhanced Raman spectroscopy (SERS) and its application to probe individual molecules are given. In Sect. 11.4, the momentum mapping of Raman scattering of individual nanostructures in the presence of optical nanoantenna is presented. Finally, in Sect. 11.7, summary and future aspects of this chapter is elaborated for the upcoming developments in the field of Raman scattering of nanostructures. |
