Abstract

Modified sol-gel processes have been developed for the preparation of precursor solutions of undoped, La and Ta doped PZT (25/75). These processes use different solvents (methoxyethanol, butoxyethanol) and different lead sources (lead acetate, lead oxide). Due to variations in the structure and in the composition of the solutions, significantly different thermal decomposition behaviors were found. These inevitably affected texture and microstructure of the sol-gel derived thin films, demonstrating the important role of precursor chemistry in the improvement of film properties. In the case of tantalum doped Pt/PZT/Pt ferroelectric capacitors a rectangular hysteresis loop, featuring high Pr, was obtained for one specific precursor chemistry.
