AI中文摘要：
金属纳米环网络可作为极具前景的柔性透明电极，这类材料是太阳能电池、触摸屏、显示器等众多应用中的关键组件。本项计算研究详细考察了两方面内容：（i）纳米环网络的电导与光学性能；（ii）该网络因电损伤发生的击穿情况。研究同时考虑了纳米环本身及其环间接触点（结点）的电阻。在（i）部分，呈现了5个参数对薄层电阻和光学透明度的影响，结果显示，若干参数组合的性能优于目前应用最广泛的透明电极氧化铟锡。在（ii）部分，由于电损伤，纳米环系统会形成一条平行于施加电压差的垂直端子的裂纹；网络退化通过其薄层电阻进行衡量，且观察到一个普适效应：不同填充因子的网络表现出相同的退化曲线。
英文摘要：
Metallic nanoring networks can serve as promising flexible transparent electrodes. These materials are crucial components in a wide range of applications, including solar cells, touchscreens and displays. In this work, a computational investigation considers in detail (i) the electrical conductance and optical performance of nanoring networks and (ii) the breakdown of these networks due to electrical damage. The electrical resistance of both the nanorings and the contacts between the rings (junctions) is taken into account. In part (i), the effects of 5 parameters on the electrical sheet resistance and optical transparency are presented. It is shown that several parameter combinations achieve better performance in comparison to indium tin oxide, currently the most widely used transparent electrode. In part (ii), due to electrical damage, the nanoring systems display the formation of a crack, running parallel to the vertical terminals, where a voltage difference is applied. The network degradation is measured by its sheet resistance, and a universal effect is observed: networks with varying filling factors exhibit the same degradation profile.
