Piezoelectric thin film, method of manufacturing piezoelectric thin film, piezoelectric element, and ink jet recording head |
摘要 |
There is disclosed a piezoelectric thin film having less non-uniform portions and holding satisfactory piezoelectric characteristics, a method of manufacturing the film, a piezoelectric element using the piezoelectric thin film, and an ink jet system recording head using the piezoelectric element. In the piezoelectric thin film of perovskite crystals formed on a substrate by a sol-gel process and represented by a general formula Pb<SUB>(1-x)</SUB>La<SUB>x</SUB>(Zr<SUB>y</SUB>Ti<SUB>1-y</SUB>)O<SUB>3 </SUB>(where 0<=x<1, 0.05<=y<=1), a film thickness of the thin film is 1000 nm or more and 4000 nm or less, and a difference between a maximum value and a minimum value of y in an arbitrary portion of the thin film is 0.05 or less. |
