Figure 4From: Revising morphology of 〈111〉-oriented silicon and germanium nanowires The total energy per atom versus the number of atoms in the unit cell for SiNWs and GeNWs. The number of formula units is proportional to NW diameter. Zero of the energy scale corresponds to the energy of the Si or Ge atom in the bulk. The lines connecting points are a guide to the eyes. For the simplicity reason Si{011} and Ge{011} denote morphology of SiNWs and GeNWs shown in Figure 1, whereas Si{112}, Ge{112} correspond to the cases in Figure 2 and Si{112}-t, Ge{112}-t indicate morphology presented in Figure 3.Back to article page
