We report a comprehensive simulation and experimental study on the optical and electronic properties of uniform and ordered copper nanomeshes (Cu NMs) to determine their performance for transparent conductors. Our study includes simulations to determine the role of propagating modes in transmission and experiments that demonstrate a scalable, facile microsphere-based method to fabricate NMs on rigid quartz and flexible polyethylene terephthalate substrates. The fabrication method allows for precise control over NM morphology with near-perfect uniformity and long-range order over large areas on rigid substrates. Our Cu NMs demonstrate 80% diffuse transmission at 17 Ω/square on quartz, which is comparable to indium tin oxide. We also performed durability experiments that demonstrate these Cu NMs are robust from bending, heating, and abrasion.
我们报告了一项关于均匀和有序铜纳米网(Cu NMs)的光学和电子特性的综合模拟和实验研究,以确定它们作为透明导体的性能。我们的研究包括模拟来确定传播模式在传输中的作用,以及实验来证明一种可扩展的、基于微球的简易方法,用于在刚性石英和柔性聚对苯二甲酸乙二醇酯衬底上制造纳米网。该制造方法允许对 NM 形态进行精确控制,在刚性衬底上实现近乎完美的均匀性和长程有序。我们的 Cu NMs 在石英上的 17 Ω/square 时表现出 80%的漫透射,可与氧化铟锡相媲美。我们还进行了耐久性实验,证明这些 Cu NMs 具有很强的抗弯曲、抗热和抗磨损能力。
