Research progress on 2D ferroelectric and ferrovalley materials and their neuromorphic application

Two-dimensional (2D) ferroelectric and ferrovalley materials have recently received extensive attention due to their significant advantages for modern electronic devices, such as miniaturization, low-dissipation, non-volatility, and multi-functionality. More interestingly, the couplings between the ferroic orders in these materials have enriched the development of intelligent devices, especially in neuromorphic computing. In this paper, the research progress of 2D ferroelectric and ferrovalley materials is introduced and the coupling effects between them are also described. Then, we briefly introduce recent neuromorphic computing reports based on 2D ferroelectric materials and give perspectives on ferrovalley neuromorphic devices.
