摘要
Tetragonal Nb-doped Pb(Zr0.3Ti0.7)O-3 (PNZT) films with a lead oxide seeding layer were deposited on the Pt(111)/Ti/SiO2/Si(100) substrates by sol-gel processing. The as-grown PNZT films with thicknesses ranging from about 0.08 to 0.78 mu m show highly a-axis preferential orientation, and their ferroelectric and piezoelectric properties improved with increasing film thickness. Due to the combined effects of Nb doping and a-axis texturing as well as reduced substrate constraint, a high d(33) constant up to 196 pm/V was obtained for PNZT film at 0.78 mu m in addition to a large remnant polarization of 69 mu C/cm(2). This well a-axis-oriented PNZT films on platinized Si with a high piezoresponse are suitable for the fabrication of microelectromechanical devices. (C) 2008 American Institute of Physics.
