Macroscale synthesis of CuO nanowires on FTO plane substrate

This study aims to fabricate copper oxide (CuO) nanowires by annealing a copper film formed on a charged film of fluorine-doped tin oxide (FTO). However, from the viewpoint of stress and growth of nanowires, it is difficult to mass-produce CuO nanowires on the entire region of the macro area on the plane substrate. In the proposed study, this was made possible by modifying the substrate’s structure.
