As the trajectory toward the graphene era continues, there is a compelling need to harness 2D technology further for the transformation of three-dimensional (3D) materials production and applications. Here, we resolve this challenge for one of the most widely utilized 3D materials in modern electronics─gold─using graphene-inspired fabrication technology that allows us to develop a multistep production method of ultrathin gold films. Such films demonstrate continuous morphology, low sheet resistance (10 Ω/sq), and high transparency (80%), offering opportunities in a variety of technological and scientific sectors. To this end, we demonstrate smart contact lenses and thermal camouflage based on ultrathin gold. Technologically, the record-breaking characteristics of ultrathin gold films open new horizons for flexible and transparent electrodes for photonics and optoelectronics. Most importantly, the demonstration of transferable wafer-scale ultrathin gold changes the paradigm of the field of 2D crystals and dramatically expands the range of available quasi-2D materials.
随着迈向石墨烯时代的轨迹持续推进，迫切需要进一步利用二维技术来变革三维（3D）材料的生产与应用。在此，我们利用受石墨烯启发的制造技术，为现代电子学中应用最广泛的3D材料之一——金，解决了这一挑战，该技术使我们能够开发出一种超薄金膜的多步生产方法。此类薄膜呈现出连续的形态、低方块电阻（10Ω/sq）和高透明度（80%），为各种技术和科学领域提供了机遇。为此，我们展示了基于超薄金的智能隐形眼镜和热伪装。从技术层面而言，超薄金膜的破纪录特性为光子学和光电子学的柔性透明电极开辟了新视野。最重要的是，可转移的晶圆级超薄金的展示改变了二维晶体领域的范式，并极大地扩展了可用准二维材料的范围。
