Extended Data Fig. 1: Variation in the unit-cell parameters of triclinic unit cells within one grain.

Unit-cell parameters at five different places (1–5) within one grain are measured in real space. The result indicates that the structure is coherent but non-cubic, with unit-cell parameters exhibiting only small deviations throughout the many-cubic micrometre grain.
