Fig. 2: The newly formed grains contain high-density dislocations.

a The initial single crystal became 13 grains. The grain boundaries are outlined by white dashed lines. The white arrow indicates the c-axis of each grain. b High density basal dislocations in grain 10. When using \(\mathop{g}\limits^{ \rightharpoonup }=\{01\bar{1}0\}\), dislocations with Burgers vector that contains \(\langle a\rangle\) component are visible. These dislocations are found to generally follow the basal plane of grain 10 (marked by a white line), and they should be basal \(\langle a\rangle\) dislocations. c High density of non-basal dislocations in grain 10. When using \(\mathop{g}\limits^{ \rightharpoonup }=\{0002\}\), dislocations with Burgers vector that contains \(\langle c\rangle\) component are visible. These dislocations are found to be out of basal plane, they should be non-basal \(\langle c\rangle\) or \(\langle c+a\rangle\) dislocations. Viewing direction, \({\sim}\langle 2\bar{1}\bar{1}0\rangle\).
