Figure 2 Epitaxial Growth of Single Crystal hBN on a Substrate

Caption

The hBN islands in (a) are unidirectional. In (b) the 3-fold symmetrical hBN shows 3 times of coincidences during the rotation form 0-360°. hBN has a 3-fold symmetry because the lattice of hBN will not be changed by rotating it by 360°/3 = 120°. (c-e) The equivalent alignments of hBN on copper surfaces (c-e), namely Cu(111), Cu(110) and Cu(100). The top layer atoms of (c),(d) and (e) show equivalent hBN alignments on substrates with 6-, 2-, 4-fold symmetries, respectively. The white shapes show the geometrical characteristic of the substrates, from which the symmetries of the substrates can be seen
