interpretation of raman spectra of disordered and amorphous carbon

Raman spectroscopy of amorphous, nanostructured,

Amorphous, nanostructured, diamond-like carbon, and nanodiamond (b) Multi-wavelength Raman spectra The three-stage model can be extended to explain spectra taken at different excitation energy. In 4 a we stressed that, for fixed excitation energy, a different sp2 configuration can result in different Raman spectra.

Raman Spectroscopy of Carbon Based Films

The investigation of the film structure of diamond-like carbon films was the main objective of this work. Films within the structural systems of hydrogenated tetrahedral amorphous carbon (ta-C:H), silicon doped hydrogenated amorphous carbon (a-C:H:Si) and nitrogen doped amorphous carbon (a-C:N) were deposited at substrate temperatures of well below 100 C. As deposition methods ion beam

[PDF] Interpretation of Raman spectra of disordered and

The model and theoretical understanding of the Raman spectra in disordered and amorphous carbon are given. The nature of the G and D vibration modes in graphite is analyzed in terms of the resonant excitation of ensuremath{pi} states and the long-range polarizability of ensuremath{pi} bonding. Visible Raman data on disordered, amorphous, and diamondlike carbon are classified in a three

2000/5/1Visible Raman data on disordered, amorphous, and diamondlike carbon are classified in a three-stage model to show the factors that control the position, intensity, and widths of the G and D peaks. It is shown that the visible Raman spectra depend formally on the configuration of the spSUP2/SUP sites in spSUP2/SUP-bonded clusters.

Interpretation of the Raman spectra of

2005/1/1The spectra observed are thus completely dominated by Raman scattering from the sp 2-bonded carbon, even when a significant amount of the carbon in the sample is sp 3-bonded . This problem can be ameliorated somewhat by the use of UV excitation for Raman measurements, where the photon energy is shifted closer to the much higher local gap of sp 3 -bonded carbon at ∼5.5 eV [7] .
