基于氧化铜纳米线的易失性数字识别忆阻器

Volatile Digit Recognition Memristors Based on Copper Oxide Nanowires


摘要(Abstract):

为了实现易失性忆阻器在神经形态计算中的应用,制备一种基于银-氧化铜纳米线-铜结构的易失性数字识别忆阻器;采用化学溶液法和磁控溅射技术,分别制备忆阻器的氧化铜纳米线阻变功能层和银顶电极;对该忆阻器的结构、物相及电学性能进行表征、测试。结果表明:该忆阻器具有易失性和突触可塑性,低阻态会在1 000 s内退化到高阻态,阻变行为由金属银原子形成的导电丝的主导作用所致;该忆阻器对手写体数字的识别准确率高达92%,可应用于神经形态计算。
