CONTINUOUS RANDOM NETWORK MODELS FOR A-AS2S3

Computer transformation techniques have been used to generate five models of a-A//2B//3 binary systems, with differing topologies, from three existing continuous random network models. The resulting structures were energy relaxed using bond stretching, bond bending and non-bonded potentials, to yield a variety of model coordinates. The atom-atom distribution functions of these models were then calculated and compared with experimental data for a-As//2S//3. The agreement in real space was found to be good for one model in particular. Furthermore, when the data were Fourier transformed to give the interference function, it was found that the model successfully reproduced the experimental diffraction pattern, including the first diffraction peak at about 1 A** minus **1.
