PIEZOELECTRIC FILM AND PIEZOELECTRIC DEVICE |
摘要 |
A piezoelectric film includes crystals of a complex oxide having a perovskite structure with (100)-preferred orientation and represented as: Pb1+δ[(ZrxTi1-x)1-yNby]Oz, where x is a value in a range of 0<x<1, y is a value in a range of 0.13≦̸y≦̸0.25, and δ and z are values within ranges where the perovskite structure is obtained and δ=0 and z=3 are standard, wherein a ratio between a diffraction peak intensity I(100) from a perovskite (100) plane and a diffraction peak intensity I(200) from a perovskite (200) plane as measured by X-ray diffraction satisfies I(100)/I(200)≧1.25. |
