  After more than a hundred years of development, ferroelectric materials have
demonstrated their strong potential to people, and more and more ferroelectric
materials are being used in the research of ferroelectric transistors (FeFETs).
As a new generation of neuromorphic devices, ferroelectric materials have
attracted people's attention due to their powerful functions and many
characteristics. This article summarizes the development of ferroelectric
material systems in recent years and discusses the simulation of artificial
synapses. The mainstream ferroelectric materials are divided into traditional
perovskite structure, fluorite structure, organic polymer, and new 2D van der
Waals ferroelectricity. The principles, research progress, and optimization for
brain like computers of each material system are introduced, and the latest
application progress is summarized. Finally, the scope of application of
different material systems is discussed, with the aim of helping people screen
out different material systems based on different needs.
