Figure 5
Crystal structure models (ball and stick on left, atom filling on right) for the relaxed structures of phases where n = 6, 8, 10 and 12 on zone axis. Layer stacks and their corresponding widths are labelled on the top of each. Atom arrangements (red = Bi, blue = Te, yellow = sulfur, green = Pb) depicting the structure are plotted along the (hkil) planes, i = −(h+k). A crystallographic information file (CIF) is provided in the supporting information. |
