摘要：

We describe how iterative, orthogonal density gradient ultracentrifugation (DGU) separations can be used to produce nearly single-chirality (6,5) SWNTs. SWNT network transistors made from these highly pure, 98% semiconducting SWNTs simultaneously exhibit high on/off ratios, mobilities, and on-state conductances, suggesting their future application in integrated circuits and near-infrared optoelectronic light emitters and photodetectors. © 2011 WILEY-VCH Verlag GmbH & Co.
