Accurate values of the refractive index of n-type InP samples have been measured at two wavelengths, n = 0.633 μm and 1.15 μm, using a near-Brewster-angle reflectivity technique. For highly doped samples (carrier concentration ≳1018 cm−3) a relationship between carrier density and refractive index has been observed which can be explained in terms of conduction band filling.
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.
