Abstract

In recent years, ferroelectric polymer-based nonvolatile memory devices have attracted much attention due to their advantages over inorganic ferroelectrics. Polarization fatigue is a major problem in ferroelectric memories and seldom studies have been reported in this field. Here we will summarize our recent work on electric fatigue in polymers as well as some of work from the other researchers. Our experimental observations indicated that the injection and the trap of space charges acted a crucial role in the origination of polarization fatigue in ferroelectric polymers.
