WebThe "native" oxide layer that forms in typical ambients must often be taken into account when measuring the thickness or refractive index of very thin films on silicon. For a typical sample of Si the refractive index and extinction coefficient at 632.8 nm are 3.88163 and 0.01896923. Below are files of complete refractive index and extinction ... WebThe refractive index of NH4Cl-H2 O solutions has been measured over a wavelength range from 496.5 to 690 nm. The NH4Cl concentration was varied from 15 to 30 wt. % over a …
