Figure 4
Analysing the complexity of various silicon carbides as a function of number of layers. (a) Complexity is plotted as a function of layers of various silicon carbide polytypes. (b) The structure of SiC 4H as viewed along the b axis, with labelled ABAC layering. Si atoms are in blue and C in black. Depending on the number of layers n in a given silicon carbide, a six- or threefold axis is present, which is reflected in the complexity measure and shows the close relation between complexity and symmetry. |
