Figure 1From: Influences of H on the Adsorption of a Single Ag Atom on Si(111)-7 × 7 Surface a The top and side views of dimmer-adatom-stacking (DAS) fault Si(111)-7 × 7 structure. The blue balls are the Si adatoms, and the pink balls are the Si rest atoms. The positions of H3, B2 and S sites are indicated in the top view within a “basin”, b the top view of 19H-Si(111)-7 × 7 model surface. The small yellow balls on the Si atoms with dangling bond are H atomsBack to article page
