Abstract: In order to fabricate high quality ferroelectric thin films qualified for ferroelectric memories, different ferroelectric thin film systems, with the structures of MFM and MFS, were deposited by using the sol-gel technique. The ferroelectric properties and the P-V hysteresis loops characteristics of these different ferroelectric thin film systems were analyzed with comparison. Based on the test results, a new practicable configuration of Ag/Pb(Zr0.52Ti0.48)O3/ Bi4Ti3O12/p-Si was fabricated, which can improve the ferroelectric properties and hysteresis loops characteristics of the ferroelectric thin films.

Key words: ferroelectric thin films, P-V hysteresis loops characteristics, sol-gel method
