From: Role of edge facets on stability and electronic properties of III–V nanowires

Figure 1

The top panel: cross sections of 〈111〉-oriented III–V NWs without (left) and with (right) small {112} facets and diameters of about 2.6 nm (the case of GaAs is shown) after full structural optimization. All facets are indicated. Pink and yellow spheres stand for III and V atoms, respectively. The bottom panel: the dependence of the total energy of GaAs NWs per the Ga-As formula unit on the number of formula units in the unit cell. The number of formula units is proportional to NW diameter. Zero at the energy scale corresponds to the energy of the GaAs formula unit in the bulk.
