Abstract

Mechanically durable transparent electrodes are essential for achieving long-term stability in flexible optoelectronic devices. Furthermore, they are crucial for applications in the fields of energy, display, healthcare, and soft robotics. Conducting meshes represent a promising alternative to traditional, brittle, metal oxide conductors due to their high electrical conductivity, optical transparency, and enhanced mechanical flexibility. In this paper, we present a simple method for fabricating an ultra-transparent conducting metal oxide mesh electrode using self-cracking-assisted templates. Using this method, we produced an electrode with ultra-transparency (97.39%), high conductance (R_s = 21.24 Ω sq⁻¹), elevated work function (5.16 eV), and good mechanical stability. We also evaluated the effectiveness of the fabricated electrodes by integrating them into organic photovoltaics, organic light-emitting diodes, and flexible transparent memristor devices for neuromorphic computing, resulting in exceptional device performance. In addition, the unique porous structure of the vanadium-doped indium zinc oxide mesh electrodes provided excellent flexibility, rendering them a promising option for application in flexible optoelectronics.

用于下一代柔性光电子技术的超透明多功能 IZVO 网状电极

具有机械耐久性的透明电极对于实现柔性光电设备的长期稳定性至关重要。此外，它们对于能源、显示、医疗保健和软机器人领域的应用也至关重要。导电网格具有高导电性、光学透明性和更强的机械灵活性，是传统脆性金属氧化物导体的理想替代品。在本文中，我们介绍了一种利用自裂辅助模板制造超透明导电金属氧化物网状电极的简单方法。利用这种方法，我们制造出了一种具有超高透明度（97.39%）、高电导率（Rs = 21.24 Ω sq-1）、较高功函数（5.16 eV）和良好机械稳定性的电极。我们还将制备的电极集成到有机光伏、有机发光二极管和用于神经形态计算的柔性透明忆阻器器件中，评估了这些电极的有效性，结果显示这些电极具有优异的器件性能。此外，掺钒氧化铟锌网状电极独特的多孔结构提供了极佳的灵活性，使其成为柔性光电子学中的一个有前途的应用选择。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
