Popis: Hydrogenated silicon-carbon alloys (Si 1- x C x :H) are studied in a cluster approach using the modified neglect of differential overlap method (MNDO-PM3). Full geometry optimizations have been performed on clusters consisting of 66 Si atoms partially replaced by C atoms in the presence of interstitial hydrogen. The resulting geometries are analyzed with respect to structural properties. The results obtained are in good agreement with the experimental data and support the idea of chemical ordering in these systems.
