    • Piezoelectric crystalline film of zinc oxide with a hexagonal crystal structure and a c-axis substantially perpendicular to the film surface, the crystalline film containing, as additive elements, vanadium and manganese together with or without copper. The piezoelectric crystalline films have high resistivity and a smooth surface, and make it possible to produce piezoelectric transducers with good conversion efficiency which can be used in a wide range of low to high frequencies. Such films can be made by a method comprising sputtering source materials, i.e., zinc oxide, vanadium and manganese together with or without copper onto a surface of a substrate to form a crystalline zinc oxide film, the sputtering being effected by using a film material source consisting essentially of a ceramic of zinc oxide containing vanadium, and manganese together with or without copper.
    • 具有六方晶系结构的氧化锌和基本上垂直于膜表面的c轴的氧化锌的压电结晶膜,该结晶膜含有或不与铜一起作为添加元素的钒和锰。 压电晶体膜具有高电阻率和平滑的表面,并且使得可以生产具有良好转换效率的压电换能器,其可用于宽范围的低频到高频。 这样的膜可以通过包括溅射源材料即氧化锌,钒和锰与铜或不含铜溅射到衬底的表面上以形成结晶氧化锌膜的方法来制造,溅射是通过使用膜材料源 基本上由含有钒的氧化锌陶瓷,以及含有或不含有铜的锰组成。
