Abstract

The radial atomic distribution of the amorphous alloy Ag0.08As0.26Se0.66 was studied, through the X-ray diffraction data supplied by samples obtained through quenching. The short-range order was determined by interpreting the Radial Distribution Function (RDF), using a theoretical expression which takes into account the variation in the atomic scattering factors with s (the scattering vector module), and approximates them to polynomic functions. The tetra- and tree-coordinated silver hypotheses, quoted in the literature for glassy alloys containing this element, were considered. The result of the study is that, for the alloy in question, only the tetra-coordinated silver hypothesis is compatible with the structural information that was experimentally obtained. A spatial atomic distribution model was generated according to this silver coordination, using the conveniently modified Monte Carlo random method. A comparative analysis of the main structural parameters of this model revealed their good agreement with the values given in the literature for similar alloys.
