Hi All I am loking some data of the dispersion of Si3N4, that is data (a table would be nice) on the refractive index n of Si3N4 vs. the wave length found by spectroscopic ellipsometry. Does anyone know where to find it, or can give me the data Kind regards/Med venlig hilsen Brian S. Semak, M.Sc. Phys.
