Schematic diagrams of lattice structures of the substrates and optical images of MoS2 grains grown on them. Unidirectionally aligned MoS2 grains can be produced on a- (a), c- (b), m- (c), n- (d), r- (e), v-Al2O3 (f), r-TiO2(110) (g), and MgO(100) surfaces (h). The orange, grey, violet and dark-blue spheres correspond to O, Al, Ti, and Mg atoms, respectively. The orange shaded planes in the lattice structures show the certain surface of the Al2O3, TiO2 and MgO substrates. The scale bars for (a–h) are the same.
