Introduction

This model mainly describes the I-V characteristic and memristive behavior of the ferroelectric tunnel junction. The I-V characteristic is modeled by Gruverman model and Fowler-Nordheim tunneling, respectively, at the low and high voltage. By setting the domain percentage to be a state variable, the memristive behavior is described by Merz’s law, KAI model and creep process model. This model can be used to simulate the FTJ-based non-volatile memory/logic circuits and neuromorphic systems.
