This peak fitting analysis allowed us to obtain specific information on the sp2 component of the composite carbon bulk material. By accurately describing the asymmetry observed in experimental spectra, we were able to distinguish between different types of carbon bonds and their respective vibrational modes. The G-band was found to arise from sp2-bonded carbon atoms, while the D and D’ bands were associated with defects and disorder in the carbon lattice. The F band was attributed to a combination of sp2 and sp3 hybridization, while the T band was related to amorphous or disordered regions within the carbon structure. Overall, this peak fitting analysis provided valuable insights into the structural characteristics of our composite material at the atomic scale.
