The aerosol deposition (AD) method utilizes high kinetic-energy submicron powders to impact and form a film on substrate. It is highly efficient method, capable of producing films or coatings with strong interfacial bonding dense nano-grain structure without thermal assistance. In this work, PbZr0.53Ti0.47O3 (PZT53/47) (~1.2 μm thick) were deposited Pt/Ti/Si(100) substrates via the AD method. After conventional annealing process (700 °C for 1 h), these PZT53/47 displayed dense, crack-free, nano-grained morphology, corresponding an optimal electrical performance. A large maximum polarization (Pmax = 70 μC/cm2) small coercive field (Ec 104 kV/cm) achieved under applicable electric 1.6 MV/cm. also exhibited small-field dielectric constant ~984, tunability 72%, low leakage current ~3.1 × 10−5 A/cm2 @ 40 V. Moreover, transverse piezoelectric coefficient (e31.f) AD-processed was as −4.6 C/m2, comparable those sputter-deposited films. These high-quality thick have broad applications in micro-electromechanical systems.
