| contents | Mechanical and Vibrational Properties of Carbon Nitride Alloys A. Champi F. C. Marques Física, Astronomía y Matemáticas Raman spectroscopy Carbon nitride alloys Mechanical and vibrational properties A study of ultraviolet and visible Raman spectroscopy was made in amorphous carbon nitride (a-C:Nx) andamorphous hydrogenated carbon nitride (a-C:Nx:H) thin films. Two growth techniques were used: 1) glowdischarge was used for depositing hydrogenated films with diamond-like (at -200V of bias) and graphite-like(-800V of bias) structure and 2) ion beam assisted deposition (IBAD) to deposit non-hydrogenated films andto obtain high nitrogen concentrations (»30%). The difference in energy between the visible and UV Raman,the so called G dispersion parameter, was investigated for both series of films. This parameter brings additionalinformation concerning the structure of the films regarding size and concentration of graphitic clusters, andqualitative information on the sp2/sp3 concentration. The characterization of the structural properties in thesefilms indicates an increase of graphite clusters with the incorporation of nitrogen. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436362 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.36 |
