Abstract

ZnO thin films with various deposition currents have been successfully fabricated by the electroplating method. The X-ray diffraction analysis showed that ZnO thin film with variations of deposition currents had a hexagonal crystal structure and crystallite sizes of 21.14 to 29.69 nm. The morphological analysis show that the deposition current increases as the grains that are formed are almost uniformly compact and cover the substrate, and the porosity is getting smaller. The results of UV-Vis spectrophotometer reveal that the transmittance value of ZnO thin films for all samples was above 80%. Bandgap values of ZnO thin films range from 3.15 to 3.24 eV.
