摘要：

Highly pure semiconducting single-walled carbon nanotubes (SWNTs) are separated from bulk materials and self-assembled into densely aligned rafts. Microscopy and spectroscopy reveals ∼100 SWNTs per micrometer within the rafts. Short channel field-effect transistors (FETs) from tens of purely semiconducting SWNTs within a submicrometer channel width achieve unprecedented on-currents (up to 121 μA) with high on/off ratios. The results demonstrate densely aligned semiconducting SWNTs for high-performance nanoelectronics. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
