(color online) Crystal structures of MoSe₂ along different direction, which is created with CrystalMaker software: (a) (100) preferred orientation with Se–Mo–Se sheets perpendicular to the substrate, (b) (110) preferred orientation with Se–Mo–Se sheets perpendicular to the substrate, (c) (002) preferred orientation with Se–Mo–Se sheets parallel to the substrate, and (d) (103) preferred orientation with Se–Mo–Se sheets tilted to the substrate.
