Electro-deposition approach was used to produce zinc oxide nanostructure thin films for switching applications in optoelectronic devices. The aqueous solution of nitrate (0.1, 0.5 & 1.0 M) and potassium (1.0M) pH 6 were prepared at 65°C with constant stirring ZnO film deposited onto indium doped tin (ITO) coated glass substrates. morphology growth size analysed by SEM. structural informatio...
