From: Revising morphology of 〈111〉-oriented silicon and germanium nanowires

Figure 2

Cross sections of 〈111〉-oriented SiNWs with morphology determined by the {112} facets. All facets are indicated. The top panel: as cut from the bulk with some surface atoms having two dangling bonds on the {112} facets to be shifted towards each other in order to form dimers. The bottom panel: after structural optimization. The diameters of the SiNWs are 1.9, 2.7 and 3.1 nm (from left to right).
