Transparent and Compact Zinc Oxide Thin Films via Two-Step Electrodeposition from Aqueous Solution
Zinc oxide films have been deposited on ITO/glass substrate by a two-step electrodeposition method from zinc nitrate aqueous solution. The two-step electrodeposition process included a potentiostatic pre-deposition and a galvanostatic deposition. Obtained ZnO film possesses high c-axis preferential orientation, smooth and compact morphology, high transmittance in the visible band, and optical band gap of 3.43eV. Compared with the film prepared by direct galvanostatic deposition, the crystalline quality and optical properties of ZnO films were significantly improved.
