Abstract

High quality c-axis oriented ZnO thin films have been successfully deposited on silicon substrates using filtered cathodic vacuum arc (FCVA) technique. Two deposition temperatures, namely room temperature and 420°C, were studied. The films were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). XRD revealed that the ZnO films exhibited (002) orientation. An amorphous layer between the substrate and the ZnO film was observed in both samples using TEM. Both samples showed c-axis oriented ZnO columns. However, for the ZnO thin film deposited at room temperature, the c-axis oriented ZnO columns were observed to grow on a layer of randomly oriented nanocrystals.
