Abstract
We present a new multi-domain model for polarization switching in ferroelectric materials. The computationally efficient model captures the time evolution of multi-domain ferroelectrics with good accuracy along with the frequency dependent switching behavior. We have fabricated (PVDF) and measured P-E characteristics of PZT and PVDF capacitors and have validated the model with measurements. The model allows the visualization of time dependent domain switching allowing further physical insights. We have also proposed a method to extract the distribution of domain orientations experimentally.
