RuO2 Nanowires and RuO2/TiO2 Core/Shell Nanowires: From Synthesis to Mechanical, Optical, Electrical, and Photoconductive Properties

Functional 1D metal oxides have attracted much attention because of their unique applications in electronic, optoelectronic, and spintronic devices. For semiconducting oxide nanowires (NWs) (e.g., ZnO, In2O3, and SnO2 NWs), field-effect transistors and light-emitting diodes have been demonstrated. Metallic oxide nanoscale materials, such as nanoscale RuO2, can be good candidates as interconnects in electronic applications. RuO2 nanomaterials have been produced by chemical vapor deposition (CVD) and through chemical reaction. Recently, RuO2 NWs have been synthesized using pure Ru as metal target under different flux ratios of O2/Ar in a reactive sputtering system. [5]
