To fabricate WS₂ nanoribbons for device applications, we investigated the growth control of WO_x nanowires as templates. Na₂WO₄/WO_x film formed by sputtering and spin coating was used as a precursor, and high-density, quasi-oriented WO_x nanowires were successfully grown by reacting with a trace amount of organosulfur. Furthermore, sulfurization of the WO_x nanowire surfaces enabled the formation of flat monolayer WS₂ nanoribbons on the WO_x nanowires.
