Four different configurations of nanostructured surfaces on solid substrate. (a) Surface 0, plate surface with no nanostructures; (b) surface 1, plat surface with nanostructures’ height of 1.8225 nm in the y-z plane; (c) surface 2, plat surface with nanostructures’ height of 3.479 nm in the y-z plane; (d) surface 3, plat surface with nanostructures’ height of 4.455 nm in the y-z plane; (e) four nanostructures’ position on solid substrate in the top view.
