The miniaturisation of structurable components produced by means of conventional (top down) techniques leads to a number of insoluble technical problems. Methods for the direct synthesis of nanostructures, such as nanotubes and nanowires (bottom up) are, however, technically possible. These can either be directly produced, or a template (host structure) can be used for their growth. A promising method for the realisation of these nanostructures is the production of Metal/Carbon Core-Shell nanostructures through the galvanic surface coating of Carbon-Nano-Tubes (CNTs) or Carbon-Nano-Bells (CNBs) with metals such as Cu or Ni. Additionally, these CNTs can, during their production, be filled in a controlled manner with metals (Cu, Ni) by means of a co-deposition process. In this way, nanostructural composite tubes (Me/C) and composite wires (C/Me) can be generated. Furthermore, the Carbon structures can subsequently be removed using an etching process, leaving metallic nanotubes or nanowires as the end product. A range of advantages with respect to mechanical stability, electrical conductivity, and optical properties, is expected to be demonstrated in these interesting materials. In this project proposal, the above mentioned possibilities for the controlled production of nanowires and nanotubes (composite, or purely metallic) are to be examined, and the range of parameters significant to their production identified. A parallel and fundamental characterisation of the structures produced, established by means of the combined use of a range of analytical methods, is to form the conclusion of the programme.

通过传统（自上而下）技术生产的可结构化部件的小型化导致了许多无法解决的技术问题。然而，直接合成纳米结构（例如纳米管和纳米线）的方法（自下而上）在技术上是可行的。它们可以直接生产，也可以使用模板（主体结构）来生长。实现这些纳米结构的一种有前途的方法是通过用铜或镍等金属对碳纳米管（CNT）或碳纳米钟（CNB）进行电镀表面涂层来生产金属/碳核壳纳米结构。此外，这些碳纳米管在生产过程中可以通过共沉积工艺以受控方式填充金属（Cu、Ni）。通过这种方式，可以生成纳米结构复合管（Me/C）和复合线（C/Me）。此外，随后可以使用蚀刻工艺去除碳结构，留下金属纳米管或纳米线作为最终产品。这些有趣的材料预计将在机械稳定性、导电性和光学性能方面表现出一系列优势。在该项目提案中，将检查上述控制生产纳米线和​​纳米管（复合材料或纯金属）的可能性，并确定对其生产具有重要意义的参数范围。通过结合使用一系列分析方法，对所产生的结构进行并行和基本的表征，从而形成该计划的结论。
