Ball-and-stick model for vdW epitaxial ZnO/hBN heterostructure. (a) Low-magnification model for (000
)[10
0]ZnO║(0001)[10
0]hBN heterostructure viewed along [0001]. The image clearly exhibits periodic triangular Moiré fringes with a periodicity of ~1.0 nm. (b) Diffraction patterns obtained through a Fourier-transform-based simulation. (c) High-magnification ball-and-stick model. (d) Two heterointerfacial atomic epitaxial relationships for the ball-to-ball (upper panel) and ball-to-hollow (bottom panel) configurations appearing in the Moiré pattern. (e) Two supercell structures of ball-top-matching (type I) and hollow-matching (type II) (3 × 3)−ZnO/(4 × 4)-BN heterojunctions for the incommensurate vdW ZnO/hBN heterostructure.
