Role of crystallographic textures on the growth of CuO nanowires via thermal oxidation

To investigate the influence of crystallographic textures on the growth of CuO nanowires, nanocrystalline cop- pers with distinct textures were fabricated using an electrodeposition. Thermogravimetric analysis, x-ray diffraction analysis, and scanning electron microscopy equipped with an electron backscattered diffraction de- tector were employed to investigate the growth of CuO nanowires at 200 ◦C and 300 ◦C. While a high number- density of nanowires was clearly observed in the (100) and (101)-textured coppers, it was not the case for the copper with strong (111) texture, indicating that the growth of CuO nanowires via a low-temperature thermal oxidation can be achieved by tailoring the texture.
