Figure 12
(a) The structure of Fig. 7(b) projected in is defined by the atomic surface union of the six Voronoi cells in grey located at the projections in of the six translation orbits. (b) The Burgers vector is contained in and thus generates no deformation of the tiles, whatever their location in the physical space as shown here. The defect (in red) is at the intersection of four translation boundaries, each conserving four among the six of the orbits forming the structure. |
