Today, carbon nanostructures are one of the most priority materials for use in various fields of science and technology, as components of new structural materials, nanoelectronics, nonlinear optics, etc. The purpose of this work was to study electrical and optical properties of multi-wall carbon nanotubes (MWCNTs) synthesized using catalysts Fe-Co with a variable composition in order to establish the relationship between the physical properties of the structure and its defectiveness. Raman scattering is widely used for characterization of various types of carbon nanostructures. This method is also sensitive to changing the structure and properties of MWCNTs. For characterization the intensity ratios of D, G and 2D-modes in the Raman spectrum have been used. It is also planned to carry out a theoretical modeling of the MWCNT Raman spectra by the first principles. The calculation will be made with the method based on density functional theory.
