TLDR
In this article, the transformation of precursors to sol, sol to gel, and gel to crystalline phase were characterized using spectroscopy and x-ray diffraction.Abstract:
Integration of ferroelectrics in the current generation of electronic/photonic devices not only enhances the functional capabilities of these devices but also has potential for a variety of new applications. The fabrication of ceramic thin films and fibers is enabled by sol-gel process. This fabrication process is well-controlled, low-cost and compatible with existing fabrication technologies. This study focussed on the fabrication of PLZT 7/65/35 ceramic thin films and fibers from lead acetate hydrate, lanthanum acetate hydrate, zirconium n-propoxide and titanium n-propoxide utilizing acid catalysis. The transformations of the precursors to sol, sol to gel and gel to crystalline phase were characterized using spectroscopy and x-ray diffraction. The films were formed by spin-coating the hydrolyzed precursor sol on various substrates: conductors (Au, Al, Pt), semiconductors (Si [100], Si [111]) and insulators (fused SiO2, Al2O3, MgO). The fibers were drawn from the similar sols. These films and fibers were...read more

The dependence of ferroelectric and fatigue behaviors of PZT films on annealing conditions
TL;DR: In this article, it was found that films with better initial polarization values did not necessarily demonstrate better fatigue behavior and the causes of film degradation as a result of switching based on the pinning of domains at grain boundaries triggered by the migration of pores is discussed.
