Modeling of Negative Capacitance of Ferroelectric Capacitors as a Non-Quasi Static Effect (1801.01842v1)

Published 5 Jan 2018 in cond-mat.mes-hall

Abstract: Pulse-based studies of ferroelectric capacitor systems have been used by several groups to experimentally probe the mechanisms of apparent negative capacitance. In this paper, the behavior of such systems is modeled through SPICE simulation with a delayed-response Preisach model, and the results are compared to available data. It is found that a simple ferroelectric domain delay model can explain much of the observed behavior, capturing the qualitatively different effects of bipolar and unipolar switching, as well as the voltage dependence of said switching. The observed behavior and its modeling suggests that the observed negative capacitance is in fact associated with ferroelectric switching, and its presence is highly sensitive to the switching frequency and other details of the ferroelectric system.
