ABSTRACT

The issues related to Raman scattering characterization of the microstructure of diamond thin films are reviewed. The optical effects of the transparent/absorbing composite of sp2/sp3 bonded material is discussed. Then the depedence of the Raman spectra on the microcrystalline size is described. The comparison is made with crystalline Si, and the analysis is applied to a series a diamond films. Lastly micro-Raman scattering from the initial stages of diamon film growth are described, and the results are correlated with STM measurements of the nuclei. Surface enhanced Raman scattering is applied to examine the regions betwen diamond nuclei.
