24_46/2012Carbon Nanotubes: High Performance Ambipolar Field-Effect Transistor of Random Network Carbon Nanotubes (Adv. Mater. 46/2012)

Selective purification of carbon nanotubes using conjugated polymers is utilized on page 6147 by Maria Antonietta Loi, Satria Zulkarnaen Bisri, and co-workers to fabricate high-performance ambipolar transistors. A device of drop-casted random-network nanotubes demonstrates high carrier mobilities and high on/off ratios for holes and electron accumulations. Together with the optical measurement results, the performance of the transistor indicates the purity of the nanotube dispersion with minimum residual polymer.
