Extended Data Fig. 3 | Statistical analysis of the orientation distribution of
triangular hBN f lakes. a, Optical micrgraph of hBN grown on a Cu (111)/
c-sapphire substrate at 1,050 °C. Misaligned hBN f lakes are marked by red
circles. b, Statistical analysis of the optical micrograph from a; more than 99.6%
of the hBN f lakes are aligned in one direction on Cu (111).
