Scanning probe microscopy, spectroscopic ellipsometry, local reflection spectroscopy, and Raman spectrometry were used to determine the correlation between the optical and structural properties of amorphous carbon-silicon a-C:H:Si films and to study the role of the atomic structure during the formation of conical nanoobjects under an electric field in a scanning probe microscope (SPM) lithograph. Based on an analysis of the experimental data, it was shown that films in the initial state are distinguished by a high disorder of the cluster structure. The film material is restructured during the SPM exposure, which is accompanied by the formation of the sp 3 -bound atomic structure and nanostructuring of the sp2-bound carbon; in this case, the refractive index decreases by a factor of ?0.6. The latter is explained by the presence of voids in the modified material.
