Optomec announced that its Aerosol Jet system has been used to fully print Carbon NanoTube (CNT) based Thin Film Transistors (TFT) with operating frequencies over 5 gigahertz (GHz). The work was conducted in collaboration with the University of Massachusetts and Brewer Science, Inc. The results were recently published in Applied Physics Letters (93, 243301 2008) with a paper titled “All [aerosol] jet-printed carbon nanotube thin-film transistor on a polyimide substrate with an ultrahigh operatin...
