Abstract

Pb(Sc_1/2Ta_1/2) O₃(PST) ferroelectric thin films with ABO₃ perovskite structure on Pt/Ti/SiO₂/Si substrate have been prepared by improved Sol-Gel process. Pb(CH₃COO)₂·3H₂O, Sc(CH₃COO)₃·xH₂O and C₁₀ H₂₅O₅Ta are used as raw materials. CH₃OCH₂CH₂OH is used as solvent. PST thin films are excellent materials for preparing ferroelectric miniature refrigerator and uncooled pyroelectric infrared focal plane arrays. The dielectric, pyroelectric and ferroelectric properties of PST thin films were measured. The ε_r and tan θ of PST thin films are 570 and 0.02, respectively. The P_x and EC of PST thin films are 3.8-6.0 μCcm^-2 and 40-45 kV·cm^-1, respectively, The pyroelectric coefficient of PST thin films are 4.0 × 10^-4-20 × 10^-4 Cm^-2K^-1.
