(color online) A schematic of hybrid X-Mo-Y nanotubes. (a) The top view of a flat hybrid X-Mo-Y material. The directions of zigzag and armchair are marked by black arrows. (b) Side view of a flat hybrid X-Mo-Y material. Different atoms at each side are labeled as X and Y. X is the element with a smaller atomic radius (O or S), and Y is the element with a larger atomic radius (S or Se). Side view of (c) a zigzag single-wall hybrid X-Mo-Y (8, 0) nanotube and (d) an armchair single-wall hybrid X-Mo-Y (4, 0) nanotube.
