Abstract

Cluster-assembled ZnO films were synthesized by using electrochemical deposition technique with various reaction times. Zinc nitrate dissolved in de-ionized water was used as a precursor of ZnO film. The as-synthesized cluster-assembled ZnO films were performed on a copper plate used as a substrate at room temperature. The stabilized high electric field of 4 kV/m was applied in the process. Field emission scanning electron microscopy (FE-SEM) was used to characterize the film morphology. The FE-SEM micrographs showed that the surface morphologies of ZnO films are clustered-like structures with aggregated nascent particles when the reaction time was increased. An energy dispersive x-ray spectroscopy (EDS) was used to monitor the films composition, consists of Zn and O with contamination-free composition and an x-ray diffractometry (XRD) showed the x-ray signal patterns of ZnO film incorporating hexagonal wurtzite crystal structures.
