Figure1.3: Truncated Si{111} Surface

Figure 1.3: Model of the ideal surface for Si{111}1x1.
The open and closed circles represent Si atoms in the first and second layers, respectively.
Closed squares are fourth-layer atoms exposed to the surface though the double double-layer mesh.
The dashed lines indicated the surface 1x1 unit-cell.
