摘要

基于二维材料的忆阻器阵列有望用于以数据为中心的应用，如人工智能和大数据。然而，访问单个忆阻器单元并有效控制潜流路径仍然具有挑战性。在这里，我们提出了一种范德华工程方法，通过将新兴的二维铁电CuCrP2S6与MoS2和h-BN组装在一起，来制造一晶体管一记忆电阻器（1T1M）电池。该存储单元具有高电阻可调性（106），低潜流（120 fA）和低静态功率（12 fW）。实验证明了一种大大减少串扰的神经形态阵列。非挥发性电阻开关是由电场诱导的铁电极化反转驱动的。这种范德华工程方法为下一代人工神经网络创建紧凑、节能的二维内存计算系统提供了一种通用的解决方案。

Van der Waals Engineering of One-Transistor-One-Ferroelectric-Memristor Architecture for an Energy-Efficient Neuromorphic Array

Two-dimensional-material-based memristor arrays hold promise for data-centric applications such as artificial intelligence and big data. However, accessing individual memristor cells and effectively controlling sneak current paths remain challenging. Here, we propose a van der Waals engineering approach to create one-transistor-one-memristor (1T1M) cells by assembling the emerging two-dimensional ferroelectric CuCrP₂S₆ with MoS₂ and h-BN. The memory cell exhibits high resistance tunability (10⁶), low sneak current (120 fA), and low static power (12 fW). A neuromorphic array with greatly reduced crosstalk is experimentally demonstrated. The nonvolatile resistance switching is driven by electric-field-induced ferroelectric polarization reversal. This van der Waals engineering approach offers a universal solution for creating compact and energy-efficient 2D in-memory computation systems for next-generation artificial neural networks.
