Figure 5
Layer stacking of (a) the zincblende structure, (b) the wurtzite structure and (c) La2O3. The left-hand column shows top views and the right-hand column side views of the close-packed structures. Large light-blue balls correspond to lanthanum atoms and small balls to nitrogen or oxygen atoms. For better visibility, different colours indicate lattice sites in different atomic planes along the stacking direction. |
