Abstract:A structural model is proposed for the metal-amorphous Ge systems, based on the filling of the inner voids by the metal in a tetrahedral CRN. This starting model is relaxed under a set of bond-stretching, bond-bending, and Me-Ge interaction potentials, for the specific case of the Cu,(a-Ge)l-, alloys (z = 0.22 and 0.40). A good agreement between the calculated and an experimental interference function is obtained by assuming an alteration of the bonding character in the a-Ge matrix towards a more metallic one.… Show more
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.
