摘要
如今,开发高性能、低能耗计算系统的一个有前途的方法是制造模仿生物突触功能的人工突触设备。这种装置在有效解决模式识别、分类、控制和治疗神经系统疾病等问题方面具有巨大潜力。该研究成果展示了一种基于锆钛酸铅(PZT)压电陶瓷和非晶磁性合金 Metglas 的复合多铁性异质结构的突触行为模仿。通过共振激发磁电(ME)效应并施加不同振幅和极性的电场脉冲,测量了异质结构的特性。ME 系数 αE 被视为突触权重,而异质结构的输出电压则被视为突触后电位。这项研究证明了在 ME 异质结构中模拟长期电位(LTP)和抑制(LTD)以及尖峰计时可塑性(STDP)的可能性。这项工作为基于多铁氧体复合异质结构创建神经形态计算系统带来了希望。
Synaptic behavior of a composite multiferroic heterostructure FeBSiC – PZT at resonant excitation
Nowadays, one of the promising ways for the development of computing systems with high performance and low energy consumption is the creation of artificial synaptic devices that imitate the functions of biological synapses. Such devices have a significant potential for effectively solving problems of pattern recognition, classification, control, and the treatment of diseases of the nervous system. The work demonstrates the imitation of synaptic behavior in a composite multiferroic heterostructure based on the piezoceramics of lead zirconate titanate (PZT) and the amorphous magnetic alloy Metglas. The characteristics of the heterostructure were measured by resonant excitation of the magnetoelectric (ME) effect and applying electric field pulses of various amplitudes and polarities. The ME coefficient αE was considered as a synaptic weight, and the output electrical voltage of the heterostructure as a postsynaptic potential. The study demonstrates the possibility of simulating long-term potentiation (LTP) and depression (LTD) in the ME heterostructure, as well as spike-timing-dependent plasticity (STDP). This work shows promise for creating neuromorphic computing systems based on multiferroic composite heterostructures.
