Aufklärung (7x7) Rekonstruktion von Si(111) mit Transmission-Elektronenmikroskopie

Surface structure of Si(111) 7x7: (top): first three layers of atoms shown in top view. The surface unit cell is outlined, (bottom): schematic view that indicates the prominent depressions in the surface (round and oval holes), the dimers (double lines) and the stacking fault (shaded region).
