In this paper, we present a new approach for making active carbon nanotube (CNT) electrical devices and demonstrate the first aligned CNT array field effect transistors (FET) from 99% pure separated semiconducting nanotubes. Through evaporation-driven deposition of predominantly semiconducting nanotubes from the liquid phase, we have fabricated aligned, thin-film CNT devices with high on-state currents. The fabrication scheme presented here provides a versatile production method translatable to other substrates such as flexible plastics.
