Medium resolution lattice images

Fig. 16.5. Atomic structure of the U connection on Au(lll). (a) Model of the atomic structure open circles, atoms of the second layer shaded circles, atoms of the top layer (dark, fee domain light, transition region medium, hep region). The dark line marks a cut along the surface atoms passing through two transition regions. This line and thus the surface atoms arc rotated by 2° relative to the bulk lattice, (b) Atomic-resolution image of the U connections. The lines correspond to the line in the model.
