Nanoscale electronic devices made from carbon nanotubes, such as transistors and sensors, are much smaller and more versatile than those that rely on conventional microelectronic chips, but their development for mass production has been thwarted by difficulties in aligning and integrating the millions of nanotubes required. Inspired by biomolecular self-assembly processes, we have created chemically functionalized patterns on a surface, to which pre-grown nanotubes in solution can align themselves in huge numbers. This method allows wafer-scale fabrication of millions of carbon-nanotube circuits with single-nanotube precision, and may enable nanotube-based devices, such as computer chips and high-density sensor arrays, to be produced industrially.
由碳纳米管制成的纳米级电子设备,如晶体管和传感器,比那些依赖传统微电子芯片的设备要小得多且用途更广,但由于在排列和整合所需的数百万根纳米管时存在困难,其大规模生产的发展受到了阻碍。受生物分子自组装过程的启发,我们在表面创建了化学功能化图案,溶液中预先生长的纳米管可以大量地自行排列在这些图案上。这种方法允许以单纳米管精度在晶圆规模上制造数百万个碳纳米管电路,并可能使基于纳米管的设备,如计算机芯片和高密度传感器阵列,能够进行工业化生产。
