dcterms.abstractWe study the hysteresis behavior of compositionally graded ferroelectric films by theoretical simulations. Anomalous vertical (polarization) shift behavior of hysteresis loops measured by a Sawyer-Tower circuit at low/medium applied fields is investigated. The anomalous ferroelectric response is discussed by the use of a multilayer model to account for the variation of properties across the film thickness. Electrical conductivities of the ferroelectric layers have been taken into account and time-dependent space-charge-limited conduction has been adopted. The effects of charge mobility and the amplitude of applied field on the D-E loop shift were examined. Theoretical calculations are discussed in relation to the experimental data from previous works.-
