Abstract: The structural and electronic properties of gold decorated Si335 surfaceare studied by means of density-functional calculations. The resultingstructural model indicates that the Au atoms substitute some of the Si atoms inthe middle of the terrace in the surface layer. Calculated electronic bandstructure near the Fermi energy features two metallic bands, one coming fromthe step edge Si atoms and the other one having its origin in hybridizationbetween the Au and neighboring Si atoms in the middle of the terrace. Theobtained electronic bands remain in good agreement with photoemission data.
