标题： Unconventional resistive switching in dense Ag-based nanowire networks with brain-inspired perspectives

摘要： 我们报告了一种在通过类似熔断操作定制的高密度自组装银纳米线网络上出现的非传统电阻切换效应。 我们提出了一种机制，通过分析这种熔断前后的电气特征来解释观察到的现象。 这一解释有助于调和早期作为透明电极使用的类似系统所得结果，以及最近尝试将此类基板用于材料内计算操作的尝试。 除了现有电阻状态的通常模拟特性以及调节内部权重的能力外，我们还表明这些网络的稀疏性和非线性行为也是其属性。 因此，通过适当调节网络密度和施加的电气协议，先前展示的纳米线编码突触行为的能力得到了神经元特性的补充。 显示英文摘要

摘要： We report an unconventional resistive switching effect on high-density self-assembled Ag-nanowire networks tailored by a fuse-like operation. We propose a mechanism to rationalize the observed phenomenology by analyzing the electrical signatures before and after such a fusing. The explanation allows reconciling the results obtained in similar systems early adopted as transparent electrodes and the more recent attempts to use this type of substrate for in-materia computational operations. In addition to the usual analog nature of the available resistance states and the ability to tune internal weights, we show that these networks' sparsity and non-linear behavior are also attributes. Thus, the formerly exhibited nanowires' abilities to code synaptic behavior are complemented by neuronal features upon properly tuning the network density and the applied electrical protocol.
