First-principles design of memcapacitors for neuromorphic computation from multiferroics

Abstract

Understanding various interactions among charge, spin, and lattice in multiferroics implies endless possibilities for material engineering. And such interactions may result in various alternative multiferroic phases that have different spin-charge-lattice combinations and thus distinct dielectric properties that can be controllable by electric field. I will talk about how to design multi-level dielectrics (memcapacitors) from the alternative phases for developing neuromorphic computations with ultralow energy consumption. And some recent experiments verying our theoretical predictions will be introduced. I will highlight the importance of first-principles design and collaboration with experiments to reveal the novel phases with multiple dielectric constants for the next-generation neuromorphic computation.
