Zinc Oxide nanostructure is the most of unique structure in the type of semiconductor. It has a specific properties and characteristics that can introduce by various morphologies. In this project, we use sol-gel method and spin coating process to characterize the properties. The XRD (X-Ray Diffraction) characterization observed the crystalline structural and the element composition of sample. This unique nanostructure we can use to get the information of the electric effect of the substrate. We use thermally stimulated current (TSC) techniques that gain the information. We found the current increased with increasing the temperature. The information is about the activation energy. We found the very small value of activation energy in the group of the below room temperature. The value of activation energy is 0.05 eV. In other word, they are all about the electric effect of the substrates.
