Figure 17
Structure map for the tetragonal chain-mail system, cmi. x and y are the in-plane crystallographic coordinates of the `from' vertex. The intensity of the image is proportional to the maximum girth of sticks, found by adjusting zc/a at each x, y. Different colours represent regions within which structures are attracted to a local maximum-girth value. The dark lines represent places where the maximum girth is zero, where sticks are forced to intersect by symmetry. At these boundaries, sticks must pass through each other to enter an adjoining region. The values of some of the peak girths are indicated. Some regions contain two maximum-girth attractors for the same weave, such as TCM2 and TCM3 (see illustration in supporting information.) |
