我们报告了一种低成本，高通量的台式方法，该方法可以通过产生超高应变速率变形，使金属薄层具有纳米级精度。激光冲击印记可以在环境条件下产生三维晶体金属结构，其超齿表面小至10纳米。该技术可成功地制造了大面积，均匀的纳米图案，其宽高比高达5，用于等离子和传感应用，以及机械增强的纳米结构和金属晶格杂种纳米电视。
We report a low-cost, high-throughput benchtop method that enables thin layers of metal to be shaped with nanoscale precision by generating ultrahigh-strain-rate deformations. Laser shock imprinting can create three-dimensional crystalline metallic structures as small as 10 nanometers with ultrasmooth surfaces at ambient conditions. This technique enables the successful fabrications of large-area, uniform nanopatterns with aspect ratios as high as 5 for plasmonic and sensing applications, as well as mechanically strengthened nanostructures and metal-graphene hybrid nanodevices.
