Document Type and Number:
WIPO Patent Application WO/2011/158492
Kind Code:
A1
Abstract:
Disclosed are: a piezoelectric film which contains a lead-free ferroelectric material and has low dielectric loss and high piezoelectric performance equivalent to that of PZT; and a method for producing the piezoelectric film.
Specifically disclosed is a piezoelectric film which comprises a (111)-oriented (NaxBiy)TiO0.5x+1.5y+2-BaTiO3 layer (0.30 ≤ x ≤ 0.46 and 0.51 ≤ y ≤ 0.62).
