摘要: 0.2Pb(Mg1/3Nb2/3)O3–0.8Pb(Zr0.5Ti0.5)O3 (0.2PMN–0.8PZT) thin films were deposited on Pt(111)/Ti/SiO2/Si [Pt(111)] and Pt(200)/SiO2/Si [Pt(200)] substrates by a sol–gel method, the effect of orientation piezoelectric dielectric properties 0.2PMN–0.8PZT was investigated. The Pt(111) Pt(200) showed strong (111) (100) preferred orientations, respectively. spontaneous polarization oriented film higher than that film. However, constant (K) transverse coefficients (d31) Because direction is more tilted away from normal to surface film, coefficient enhanced.
