Reliable, inexpensive and printable electronics are within reach thanks to work by scientists from DuPont and Cornell University, who have found a way to produce volumes of semiconducting ink that can be made into improved nanotubes.
Working under the sponsorship of the Air Force Office of Scientific Research, the research team developed a method that “separates metallic and semiconducting nanotubes by attaching fluorinated molecules to their walls,” a spokeswoman says, adding that the intended result is to eliminate short-outs in transistors.
