Schematic illustration of the orientation relations between the wurtzite-type and the NaCl-type phase of ZnO. Stereographic projections perpendicular to the [001]W direction of the wurtzite type: the {100} poles of the NaCl-type phase are shown. Open and solid circles (ellipses) indicate poles on the upper and on the lower hemisphere, respectively. (a) Measured positions of the NaCl-type {100} poles. (b) Underlying orientations of the 12 NaCl-type unit cells relative to that of the wurtzite type. The unit cells of the NaCl-type structure are tilted by approximately 15° around axes very close to the 〈100〉 directions of the original wurtzite-type crystal. The {100} poles of two orientations rotated around axes close to [010]W are marked with blue and red. The pairs of adjacent poles could not be resolved on the photographs.
