Copper zinc oxide (CuZn)O thin films were fabricated on indium tin oxide-coated glass substrates using the cathodic electrochemical deposition method under various conditions. These included different temperatures, deposition times, and potentials. The deposition solution contained 1 mM Cu(NO3)2 and various concentrations of Zn(NO3)2. X-ray diffraction demonstrated that wurtzite structure for films deposited at 60°C, whereas samples that deposited at room temperature were amorphous. In the visible region, the samples exhibited high optical transmission, i.e., larger than 65%. Conductivity was found to be p-type by photoelectrochemical characterizations for the samples fabricated at room temperature. In contrast, the films fabricated at 60°C were n-type or close to intrinsic.
