Amorphous silicon carbide and silicon nitride thin films have attracted much attention in the last years because of their excellent physical and mechanical properties. Amorphous silicon-carbon-nitride (a-SiCN) belongs to a new class of ternary compound materials which show excellent mechanical properties, low friction coefficient, wide band gap, high refractive index and high chemical inertness.
OSA | Refractive Index of Silicon
The refractive index of silicon was measured at room temperature over the range 1.1–2.0 μ by autocollimation in an ~12° wedge. The image was observed by sweeping it across a slit in front of a lead sulfide cell whose output was displayed vertically on an oscilloscope while the sweep frequency was displayed horizontally. The problems of measuring the refractive index of silicon are

SiC is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Si4+ is bonded to four equivalent C4- atoms to form corner-sharing SiC4 tetrahedra. There is three shorter (1.89 Å) and one longer (1.91 Å) Si–C
Silicon carbide is used in abrasives, in polishing and grinding. It is widely used in appliions calling for high endurance, such as automobile brakes, car clutches and ceramic plates in bulletproof vests. Electronic appliions of silicon carbide are as light emitting
Measurement of thickness profile and refractive index …
The proposed system was demonstrated with two translation stages and the thickness profile and refractive index variation of a 100 mm silicon wafer along its center line were measured. The measured thickness profile showed a wedge-like shape with a maximum deviation of 2.03 μm at an average geometrical thickness of 478.03 μm.

In this work, optical coatings with a gradient of the refractive index are described. Its aim was to deposit, using the RF PECVD method, films of variable composition (ranging from silicon carbon-oxide to silicon carbon-nitride) for a smooth change of their optical properties enabling a production of the filter with a refractive index gradient. For that purpose, two organosilicon compounds
