Ferroelectric Properties of Sol-gel Derived Ca1-xSrxBi4Ti4O15 Thin Films

摘要：

　　Ca1-xSrxBi4Ti4O15 thin films were fabricated by sol-gel method on Pt(100)/Ti/SiO2/Si substrates.Influence of Sr content on the microstructure and ferroelectric properties of Ca1-xSrxBi4Ti4O15 thin films were systematically studied.The results indicate that Ca0.4Sr0.6Bi4Ti4O15 thin film has better ferroelectric properties with remanent polarization (2Pr) of 29.1μC/cm2,coercive field (2Ec) of 220 kV/cm.Furthermore,the film has good fatigue resistance.The better ferroelectric properties of Ca0.4Sr0.6Bi4Ti4O15 thin film originate from the relatively high concentration of a-axis oriented grains.
