An accumulation of the hysteresis loss energy can prove detrimental to the capacitor, especially in high-frequency applications. As such, there is an urgent need to evaluate the effect of hysteresis on the long-term operation performance of AFE capacitors.
The difference in the fields between the forward and reverse transition is termed electric hysteresis. As accumulation of hysteresis loss is detrimental to antiferroelectric capacitors, especially in high-frequency applications, the effect of hysteresis on the long-term operation performance must be evaluated.
This paper reports a semi-empirical, SPICE compatible and computationally efficient compact model for ferroelectric capacitors (Fe-CAP) description. This compact model is inspired by the Jiles–Atherton model of ferromagnets, which features significantly smaller computational effort than other state-of-the-art models.
The large hysteresis composition is (Pb 0.97 La 0.02 ) (Zr 0.59 Sn 0.31 Ti 0.10 )O 3 and is abbreviated as PZ-L (L: large hysteresis). The effect of hysteresis on fatigue mechanism, its manifestation on maximum polarization, strain and energy storage properties are thoroughly investigated.
It is a ferroelectric capacitor model only, hence it can be included onto a BSIM model. The ferroelectric thickness, permittivity, and fitting parameter are defined within the model file, or these can be included during simulation.
1. Introduction The rapid increase in energy generation from renewable resources, especially over the last decade, has led to a growing demand for high energy-density capacitors.
