Structuring two-dimensional transition metal dichalcogenide sheets as nanoribbons has tremendous potential for electronic state modification due to quantum confinement and edge effects. In this study, WS₂ nanoribbons were successfully grown on W_xO_y nanowires by chemical vapor deposition method using transition metal salts and organosulfur. The WS₂ nanoribbons were monolayer with a very high yield (~100%), which was attributed to the self-limiting growth mechanism at the atomic-scale surface of W_xO_y nanowires.
