Abstract
Short-range orders of Cd x Se 70− x Te 30 amorphous alloys of a chalcogenide system with 2≤ x≤10 have been studied by wide-angle X-ray scattering (WAXS). Once the hypotheses on the local order of the alloy had been formulated, the radial distribution function (RDF) analysis have make it possible to evaluate them referring specifically to the coordination of the atoms. The structural parameters such as atomic distance between the different possible pairs of atoms in each element J( r), the structure factor F( q), the pair distribution function G( r) and the coordination numbers for amorphous samples have been discussed. Moreover, in our system, under study, the average coordination numbers of the three different atoms involved and their distance to the first coordination sphere have been determined. However, the extraction of the inverse Fourier transforms to generated atomic distribution function has led us to a simulated reduced interference function Q( q).
