Geometric relations for the wurtzite lattice structure along the [[1\bar{1}00]] growth vector. The lower graph shows the same lattice arrangement turned 90° clockwise around the horizonal axis of [[00\bar{1}0]] orientation, with grey atoms and bonds added to facilitate comparison with Fig. 12[link]. Lattice vectors are shown in blue, whereby only a3 and c are relevant in the [\{1\bar{1}00\}] plane. For {0021} interfaces, a3 can be alternatively described by a combination of a1 and a2, again shown in grey underneath the orthogonal vector of the respective interface on the left side of the top graph. Orthogonal vectors which are not part of the {0021} interface class are shown by grey arrows and respective indices in smaller grey print. Distance increments for the {0021} interfaces sIF,0021 and the {0001} interfaces sIF,0001 are shown in purple. The unit area for this cross section A[_{\tallrectangle}] is shown as a hatched grey–green rectangle.
