Size distribution, Young’s moduli and electrical resistivity are investigated for CuO nanowires synthesized by different thermal oxidation methods. Oxidation in dry and wet air were applied for synthesis both with and without an external electrical field. An increased yield of high aspect ratio nanowires with diameters below 100 nm is achieved by combining applied electric field and growth conditions with additional water vapour at the first stage of synthesis. Young’s moduli determined from resonance and bending experiments show similar diameter dependencies and increase above 200 GPa for nanowires with diameters narrower than 50 nm. The nanowires synthesized by simple thermal oxidation possess electrical resistivities about one order of magnitude lower than the nanowires synthesized by electric field assisted approach in wet air. The high aspect ratio, mechanical strength and robust electrical properties suggest CuO nanowires as promising candidates for NEMS actuators.

Cupric oxide (CuO) nanowires (NWs) on Cu-foils were prepared by thermal oxidation method in air atmosphere using two annealing manners (continuous and steps) in the temperature ranges of 400–500[Formula: see text]C and 400–600[Formula: see text]C. Morphology and microstructure of the NWs was studied using field effect scanning electron microscopy (FESEM), X-ray diffractogram (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED). Optical reflectance spectrum was used for the optical investigation of the layers. We found the NWs formed have two different morphologies, curved and straight, with diameters between 50 nm and 200 nm and lengths between 5 [Formula: see text]m and 10 [Formula: see text]m. SAED pattern of a single NW revealed as a CuO single crystal with monoclinic structure. The reflectance spectra analysis based on Kubelka–Munk method showed that the band gap energy of the CuO NWs are varying in the range of 1.40–1.47 eV depending on the crystallite sizes of the NWs, a confirmation for the happening of the quantum confined effect in these samples.

In this paper, the synthesis and characterization of uniform and dense CuO nanowires on fluorine-doped tin oxide (FTO) glass substrate are reported. The procedure simply involved the vapor–solid thermal oxidation growth process of CuO nanowires on FTO surface in the air flow. The sample was annealed in air within the temperature range 300–600°C for 1 h. The morphology and density of the CuO nanowires could be controlled by annealing temperature. The SEM image analysis indicates that the nanowires feature uniform size with aligned structures. The high-resolution transmission electron microscopy (HRTEM) result of individual CuO nanowires shows that the nanowires were single-crystalline, and the selected area diffraction pattern (SEAD) of the same sample shows that the nanowires grow along the (110) direction. The XRD analysis shows that CuO was the only product when the sample annealed at the temperature higher than 500°C.
