Abstract
Electric depolarization fields generated by a stripe domain structure in ferroelectrics are considered within a semiconductor model. Field screening due to electronic band bending and due to presence of intrinsic defects leads to the building of asymmetric space charge regions near the grain boundary. This in turn results in the formation of a potential barrier between the grain surface and its interior.
