Reflectance anisotropy of uracil covered Si(0 0 1) surfaces: Ab initio predictions

Reflectance anisotropy spectra (RAS) for energetically favored models of uracil covered Si(0 0 1) surfaces have been calculated within the independent particle approximation. While for low coverages mainly an attenuation of the features typical for the clean surface is found, the calculations predict the appearance of new peaks for higher coverages, suggesting the usage of RAS for the analysis of organic/inorganic interfaces.
