The refractive indexes and their variations with temperature for silicon and germanium have been measured over the 95-298-K and 2.5-12-microm ranges. Data are given for the refractive index that are in reasonable agreement with those of previous investigators. For dn/dT the values are independent of wavelength and are approximately 1.5 x 10(-4) (K)(-1) and 4.0 x 10(-4) (K)(-1) for silicon and germanium, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
