The ordinary refractive index of 6H SiC has been measured from 2.43 μ (0.51 eV) to 0.336 μ (3.69 eV), using the transmission interference fringes of thin plates. Thibault’s data in the visible were used to normalize the dispersion curve. The index goes from 2.530 at 0.51 eV to 2.868 at 3.69 eV. The residual-ray and interband contributions to the index are evaluated. The extrapolated

Silicon forms a nearly-ideal surface layer of SiO2 when exposed to oxidizing environments. The "native" oxide layer that forms in typical aients must often be taken into account when measuring the thickness or refractive index of very thin films on silicon.
What is the Silicon Wafer Refractive Index? Below is the refractive index of silicon wafers. According to the formula where e0 = 11.67 is static permittivity, refractive index of silicon tends to 3.416, when wavelength tends to infinity (to 1000 μm and more in our case).
