碳纳米管作为分子线具有广阔的前景，因为它们具有高导电性和化学稳定性。然而，构建基于纳米管的电子设备需要一种受控的组装管的方法。我们报告了生产单个短单壁碳纳米管片段及其在化学功能化纳米光刻模板上可靠沉积的程序。使用这种方法，我们将单个纳米管放置在特定的位置和方向，使纳米管接触金属电极。这一发现对于用纳米管制造简单电路可能非常重要，并为研究纳米管中的电子传输提供了新工具。 (C) 1999 Elsevier Science B.V. 保留所有权利。
Carbon nanotubes offer great promise as molecular wires because they exhibit high electrical conductivity and chemical stability. However, constructing nanotube-based electronic devices requires a controlled means of assembling the tubes. We report procedures both for producing individual short SWNT segments and for their reliable deposition on chemically functionalized nanolithographic templates. Using this method, we have positioned individual nanotubes at specific locations and orientations in such a way that the nanotubes contact metal electrodes. This discovery is potentially very important for fabrication of simple electrical circuits with nanotubes, and provides a new tool for study of electron transport in nanotubes.
