| 中文摘要 | Temperature-dependent ferroelectric fatigue behaviors of layered-perovskite thin films Bi4-xLaxTi3O12 (BLTx), prepared by sol-gel method, were studied in this paper. Well-saturated hysteresis loops were observed for all samples. The switching fatigue testing at room temperature demonstrates that the fatigue resistance performance can be improved with increasing La-doping content from 0.25 to 0.75, which is attributed to the enhanced activation energy for diffusion of oxygen vacancies. The fatigue experiments close to room temperature and at low temperature indicate that the fatigue behaviors over the two temperature ranges are dominated by oxygen vacancies and space charges, respectively. The temperature point separating the two ranges is about 220 K and 240 K for BLT0.75 and BLT1.0 thin films, respectively. |
