Optical Properties of Polymeric Sulfur Nitride,(SN)x

Abstract
We report polarized reflectivity measurements on crystalline (SN)x in the range of 0.25-6.0 eV. Our analysis of the data gives ωp=4.6 eV and m*=2me,, values considerably different from those previously reported by other workers. The data also suggest that (SN)x has sufficient electronic dimensionality to suppress a Peierls distortion.
