| Abstract | MoO2 nanowires (NWs), MoO2/MoS2 core–shell NWs, and MoS2 nanotubes (NTs)weresynthesized by the turbulent flow chemical vapor deposition of MoO2 using MoO3, followed by sulfurization in the sulfurgas flow. The involvement of MoOx suboxideis suggested by density functional theory (DFT) calculations of thesurface energies of MoO2. The thickness of the MoS2 layers can be controlled by precise tuning of sulfur vaporflow and temperatures. MoS2 had an armchair-type windingtopology due to the epitaxial relation with the MoO2 NWsurface. A single ∼ few-layer MoO2/MoS2 core–shell structure showed photoluminescence after the treatmentwith a superacid. The resistivities of an individual MoO2 NW and a MoS2 NT were measured, and they showed metallicand semiconducting resistivity–temperature relationships, respectively. |
