Figure 5
Schematic representation of the scan dimensionality for different symmetries: (a) a general case, initial pattern has symmetry p1, 3D cell search. Left side: the (hk0) plane showing the a0 and b0 vector definition and the base of the unit cell for the cell search; right side: a scheme for the grid search in reciprocal space. The z axis represents V*. Scans are performed in layers of constant V*, varying the x* and y* components of the vector c. (b) The initial pattern has symmetry pmm, reducing the search to a 2D search along four mirror planes; (c) initial pattern with symmetry cmm – 2D search along three mirror planes; (d) initial pattern corresponding to a mirror plane (e.g. monoclinic crystal system, initial pattern [010] zone) and higher symmetries – 1D scan. |
