【Abstract】 The main hindrance to commercial applications of ferroelectric thin films due to their electric fatigue problems under ac electric fields has been well recognized. Significant researches have been carried out in an effort to understand the electric fatigue behavior and failure mechanism of ferroelectric thin films. In this paper, recent progress on the electric fatigue of ferroelectric thin films was briefly reviewed in terms of the factors that influence the fatigue behavior, the mechanism by which the ferroelectric thin films failed due to electric loading and the ways through which the fatigue was mitigated. Possible solutions to reduce or minimize the electric fatigue of ferroelectric thin films were also summarized.更多还原
