A network of silver nanowires (Ag-NWs) is grown by electrodeposition in a nanoporous membrane with interconnected nanopores. This bottom-up approach fabrication method gives a conducting network with a 3D architecture and a high density of Ag-NWs. The network is then functionalized during the etching process, which leads to a high initial resistance as well as memristive behavior. The latter is expected to arise from the creation and the destruction of conducting silver filaments in the functionalized Ag-NW network. Moreover, after several cycles of measurement, the resistance of the network switches from a high-resistance regime in the GΩ range with tunnel conduction to a low-resistance regime presenting negative differential resistance in the kΩ range.
通过在具有相互连接的纳米孔的纳米多孔膜中进行电沉积生长银纳米线（Ag-NW）网络。这种自下而上的制造方法产生了具有三维结构和高密度Ag-NW的导电网络。然后在蚀刻过程中对该网络进行功能化，这导致了高初始电阻以及忆阻行为。预计后者源于功能化Ag-NW网络中导电银细丝的形成和破坏。此外，经过几个测量循环后，网络的电阻从具有隧道传导的GΩ范围内的高电阻状态切换到kΩ范围内呈现负微分电阻的低电阻状态。
