Figure 2
Sketch of a triclinic crystal cell oriented with its (001) net plane parallel to the xy plane. For studying more general orientations with, e.g., a (−1−10) contact plane, all planes and vectors have to be rotated around the zone axis [1−10] by the angle Φ. The zone axis is defined by the vector n, being orthogonal to σ1 and σ2. As visualized in the right part of the figure, lattice planes as well as crystallographic directions follow this transformation. |
