In an experimentally simple replica process, the natural flatness of mica or polished silicon wafers can be transferred to metal films, resulting in metal surfaces with topographic features in Angstrom dimensions over large areas. Two decades after its invention, the template-stripping process continues to appeal to scientists from diverse research backgrounds primarily due to its simplicity, cost-effectiveness and ability to yield high quality substrates and structures. This article introduces the basic construction process for template-stripped substrates, and reports on a variety of extensions of the process, including the generation of materials contrasts and the design of tailored topographies. It also highlights the use of such substrates in a variety of research fields in nanoscience and technology ranging from surface force measurement and high definition imaging to the self-assembly of model membranes and plasmonics.
在一个实验上简单的复制过程中，云母或抛光硅片的自然平整度可以转移到金属薄膜上，从而在大面积上得到具有埃米级形貌特征的金属表面。模板剥离工艺发明二十年后，仍然吸引着来自不同研究背景的科学家，主要是因为其简单、经济高效，并能够产生高质量的衬底和结构。本文介绍了模板剥离衬底的基本构建过程，并报告了该过程的各种扩展，包括材料对比度的产生和定制形貌的设计。它还强调了这种衬底在纳米科学和技术的各种研究领域中的应用，从表面力测量和高清晰度成像到模型膜和等离子体的自组装。
