Preparation and characterization of TiO2 nanowire - Cu2O nanocube composite thin film

Composite of TiO2 nanowire and Cu2O nanocube has been prepared. TiO2 nanowire with ~240 nm in thickness and 20 nm in length were synthesized by using liquid phase deposition (LPD) method at 50�C for 4h on ITO substrate. The anatase phase of TiO2 nanowire was obtained by annealing the samples at 400�...
