Figure 8
Bonds length contributions to dsub for the seven single-module phases (n = 0, 2, 4, 6, 8, 10 and 12). The Pb—S contribution is shown in blue, and others (Bi—Te, Bi—S and Te—Te) are shown in orange. The two types of bonds display contrasting trends: the contribution from Pb–S increasing from the 5- to 17-atom layer, whereas the contribution of other bonds systematically decreases. |
