Length-Sorted, Large-Diameter, Polyfluorene-Wrapped Semiconducting Single-Walled Carbon Nanotubes for High-Density, Short-Channel Transistors
Samples of highly enriched semiconducting
SWCNTs with average diameters
of 1.35 nm have been prepared by combining PODOF polymer wrapping
with size-exclusion chromatography. The purity of the material was
determined to be >99.7% from the transfer characteristics of short-channel
transistors comprising densely aligned sc-SWCNTs. The transistors
have a hole mobility of up to 297 cm<sup>2</sup>V<sup>–1</sup> s<sup>–1</sup> and an On/Off ratio as high as 2 × 10<sup>8</sup>
