The multiple ferroelectric polarization tuned by external electric field could be used to simulate the biological synaptic weight. Ferroelectric synaptic devices have two advantages compared with other reported ones: One is the intrinsic switching of ferroelectric domains without invoking of defect migration as in resistive oxides contributes reliable performance in these ferroelectric synapses. Another tremendous advantage is the extremely low energy consumption because the ferroelectric polarization is manipulated by electric field which eliminate the Joule heating by current as in magnetic and phase change memory. Ferroelectric synapses are potential for the construction of low-energy and effective brain-like intelligent networks. Here we summarize recent pioneering work of ferroelectric synapses involving the structure of ferroelectric tunnel junctions (FTJs), ferroelectric diodes (FDs) and ferroelectric field effect transistors (FeFETs), respectively, and shed light on future work needed to accelerate their application for efficient neural network.

铁电突触的最新进展、前景和挑战

通过外部电场调节的多重铁电极化可用于模拟生物突触权重。与其他报道的装置相比，铁电突触装置有两个优点：一是铁电域的固有切换，而不会引起缺陷迁移，因为电阻氧化物在这些铁电突触中提供了可靠的性能。另一个巨大的优势是极低的能量消耗，因为铁电极化是由电场操纵的，这消除了磁和相变存储器中电流的焦耳热。铁电突触具有构建低能量和有效的类脑智能网络的潜力。
