Figure 2 Epitaxial Growth of Single Crystal hBN on a Substrate (image) Institute for Basic Science Share Print E-Mail 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 Credit IBS Usage Restrictions Please indicate the credit:IBS.
