The effects of excess Pb and Zr/Ti ratio on crystallization behavior and ferroelectric properties of sol-gel derived films were studied. Excess Pb was found to reduce the crystallization temperature. Films with good ferroelectric properties (remanent polarization greater than 8 μC/cm2 ) were achieved after 550 °C, 5 minute crystallization. The difference in the magnitude of the charge in response to switching and non-switching pulses was greater than 1 μC/cm2 after 1011 fatigue cycles for many of the films. The arnount of charge remaining after fatigue was found to be dependent on the initial charge. Reducing the partial pressure of oxygen during crystallization affected both the remanent polarization and fatigue behavior. The fatigue rate was relatively independent of composition and crystallization temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
