Abstract
We have studied influence of processing parameters on the microstructure and ferroelectric properties of lead zirconate titanate (PZT)-based thick films in the range of 5–25
μm. PZT and 2% La-doped PZT thick films were processed using a modified sol–gel process. In this process, PZT- and La-doped PZT powders were first prepared via sol–gel. These powders were calcined and then used with respective sols to form a slurry. Slurry composition was optimized to spin-coat thick films on platinized Si substrate (Si/SiO
2/Ti/Pt). Spinning rate, acceleration and slurry deposition techniques were optimized to form thick films with uniform thickness and without any cracking. Increasing solids loading was found to enhance the surface smoothness of the film and decrease porosity. Films were tested for their electrical properties and ferroelectric fatigue response. The maximum polarization obtained was 40
μC/cm
2 at 250
kV/cm for PZT thick film and 30
μC/cm
2 at 450
kV/cm for La-doped PZT thick film. After 10
9 cycles of fatiguing at 35
kHz, La-doped PZT showed better resistance for ferroelectric fatigue compared with un-doped PZT films.
