主要研究成果

1. 研究了NbO2忆阻器神经元的尖峰动力学特性及不同特性之间的转化边界,演示了如何将生物的簇发放(Bursting)动力学融合到人工神经网络之中,通过构建感知器实现了模式分类功能,并将簇发放信号在神经元之间进行传递。

2. NbO2中观察到的复杂负微分电阻(NDR)现象为基础,创新性地提出并在实验上证明了关于NDR现象的一种独立于材料种类和物理机制的普适性模型;探索了基于负微分电阻效应的NbO2电子弛豫振荡器,研究了单个振荡器和耦合振荡器的动力学特性,用于以小型耦合振荡网络为基础的神经形态计算。

3. 利用COMSOL有限元建模,揭示了电阻开关中电子预处理的软击穿过程和复位过程,并研究了包含NbOx在内的多种过渡金属氧化物中电阻开关效应的影响因素。

4. 在国际上最早选用NbO2作为选通器材料解决交叉型存储阵列中的漏电流通路问题,创新性地引入双层氧化物(WOx/NbOx)结构,实现了选通器-存储器组合功能,实现阻变存储器高密度应用。
