Crystalline properties of rf-sputtered ZnO film on gold film on fused quartz

Abstract
The effect of the crystalline properties of gold film on those of ZnO film was investigated in detail for a ZnO/gold/fused quartz structure. The investigations were done using x-ray diffraction and a rocking curve method. It was found that the crystalline properties of rf-sputtered ZnO films were strongly dependent on those of gold films. Transducer efficiency was also determined for this structure. It was found that the ZnO/gold/fused quartz structure had a high transducer efficiency, if the ZnO film was fabricated on the gold film whose σ for the (111) rocking curve was less than 3°.
