The effects of carbon incorporation on the refractive

Apr 23, 2020· A possible explanation of the behavior in the second regime involves the formation of silicon carbide bonds in the layers. The refractive index of Si–C is near 2.0. An increase in the Si–C bonding concentration would therefore increase a layer’s refractive index, potentially countering any effect of increase in the porosity.
