摘要
忆阻器是一类具有记忆作用的电阻器件,它的忆阻值可以由通过器件的电荷或通量精准调控,在电激励信号撤去之后,其忆阻值也能保持。利用纳米尺度下流体中一些特殊的传输现象,建立了基于纳流体通道系统的界面型忆阻器。通过一系列电学测试,实现了对纳流体器件电导值连续且非易失的调控作用,证明了该器件的忆阻特性。同时,通过在纳米通道的两端注入互不相溶的两种液体,模拟了重要的生物突触功能,展现了纳流体器件在类脑研究计算方向的应用潜能。
A memristor is a resistive device with an inherent memory.The memristance of a memristor shows strong dependence of the charge or flux passes through it,which is retained after stopping electrical stimuli.By exploiting some special transport phenomenon in nanoscale,a novel interfacial memristor based on nanochannel system is reported here.The mechanism of continuous and non-volatile conductance tuning is identified through electrical measurements,thus verifying the memristive characteristics of this device.By injecting KCl solution and ionic liquid BmimPF6 as the electrolyte media into the nanochannel,we successfully imitate important biological synapse functions,indicating great potential in applying nanochannel memristor into neuromorphic computing.
