| Research Abstract |
Copolymers of vinylidene fluoride are high-performance ferroelectrics, although their microscopic understanding is missing due to their complex structure. In this study, we clarified the polarization reversal process microscopically by use of a piezoresponse force microscope that scans the distribution of polarization with a cantilever. We also measured the polarization reversal process at very short time and found that these polymers show very quick polarization reversal. In addition, we manufactured memory devices with a ferroelectric polymer and clarified the electronic behavior in these devices.
