Abstract: A method of fabricating a zinc oxide thin film by a sputtering process, wherein a substance, such as boron, having an ion radius smaller than that of zinc is sputtered in an oxygen atmosphere. A body of zinc and a body of such a substance may be separately provided as targets of a cathode so that such separate targets may be simultaneously sputtered to thereby produce a thin film such as mentioned above. Alternatively, use may be made of a cathode provided with a zinc target having a substance buried therein which has an ion radius smaller than that of zinc.

Abstract: Ferroelectric ceramic compositions consisting essentially of quaternary solid solutions of Pb(Fe1/2.Nb1/2)O.sub.3 --Pb(Zn1/3.Nb2/3)O.sub.3 --PbZrO.sub.3 --PbTiO.sub.3, the components of which are within a defined range of relative proportions, have substantially higher insulation resistance characteristics and substantially higher electromechanical coupling coefficient characteristics than prior art compositions. Additionally, the components within a more restricted range of relative proportions have the additional characteristic of a higher Poisson's ratio than prior art compositions.
