Ferroelectric and Piezoelectric Materials

It has been widely observed in ionic donor-acceptor charge-transfer (CT) compounds that kink-type domain walls between one-dimensional ferroelectric molecular domains show strong dielectric response with a thermally activated relaxation frequency over a wide temperature range. The domain walls can carry spin and electric charge, which produce anomalous charge-transport phenomena observed in this type of CT dielectrics.
