Nanotube electronics: Large-scale assembly of carbon nanotubes

Saleem G. Rao1, Ling Huang1, Wahyu Setyawan1 & Seunghun Hong1,2

Nanoscale electronic devices made from carbon nanotubes, such as transistors and sensors1, 2, 3, 4, 5, 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.
