Abstract

Poly-crysial ZnO films with c-axis (002) orientation have been successfully grown on the 64° LiNbO3 substrate by RF magnetron sputtering technique. The deposited films were characterized as a function of deposition temperature, argon-oxygen gas flow ratio and the chamber pressure. Crystalline structures of the films were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM) observations. Highly (002) oriented films can be obtained. Love wave devices based on this structure (ZnO/IDTs/64° LiNbO3) were then presented. Preferred deposition condition was found to give good film quality for resonator filter and sensor applications, respectively.
