    摘要: Piezoelectric crystalline film on a substrate, which is a crystalline zinc oxide film with a c-axis substantially perpendicular to the substrate surface, the crystalline zinc oxide film containing, as an additive element, phosphorus. The piezoelectric crystalline films have high resistivity and a smooth surface, and make it possible to produce piezoelectric transducers with good conversion efficiency. Such films are made by sputtering zinc oxide and phosphorus onto a substrate from a film material source consisting essentially of a ceramic of zinc oxide containing phosphorus.

    摘要: 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.
