vdW heteroepitaxial relationship of ZnO/hBN investigated by plan-view TEM. (a) Plan-view low-magnification TEM image of ZnO nanoneedles grown on few-layer hBN. (b) Plan-view high-resolution transmission electron microscopy lattice image displaying in-plane epitaxial relationship of ZnO/hBN. Diamond-shape Moiré patterns are repeatedly observed every 1 nm. (c) Selected-area electron diffraction patterns obtained from the area shown in the inset (scale bar, 100 nm). (d) Intensity profile of the electron beam diffraction of ZnO (10
0) as a function of the central angle.
