波浪形金属材料在各种应用中发挥着重要作用。目前这种材料的合成策略仅限于自顶向下的薄金属膜蚀刻。请注意，自顶向下的蚀刻不可避免地要比自底向上的类似物处理更多的表面悬挂键，并导致化学稳定性差。然而，到目前为止，还没有自下而上的方法来生产波浪形金属材料。在这里，以铜作为模型材料，自下而上的两阶段隧道主导的电沉积策略，据报道，以产生超长的铜波形微结构（WMS）的光刻图案化和原生氧化层钝化的硅电极，其中直接电子转移受阻。扫描电子显微镜和场发射扫描电子显微镜的结果表明，大规模生产的铜WMS组成的相互连接的八面体和立方八面体纳米粒子。I-V曲线表明沉积态Cu WMS具有良好的电学性能。一起...
Wavy-shaped metallic materials play a significant role in various applications. The current synthesis strategy for such materials is limited to top-down thin metal film etching. Note that top-down etching is inevitable to process more surface dangling bonds than their bottom-up analogues and results in poor chemical stability. However, up to now, no bottom-up method has been presented to produce wavy-shaped metallic materials. Here, taking Cu as a model material, a bottom-up two-stage tunneling-dominated electrodeposition strategy is reported to produce ultralong Cu wavy microstructures (WMSs) on a lithographically patterned and native oxide layer-passivated Si electrode, where direct electron transfer is impeded. Scanning electron microscopy and field-emission scanning electron microscopy results demonstrate the large-scale production of Cu WMSs consisting of interconnected octahedral and cuboctahedral nanoparticles. The I–V curve suggests good electrical performance of the as-deposited Cu WMSs. Together...
