Superior Nanotube Film for High Performance Field Effect Transistors
UW-Madison researchers have developed a method to make a dense, highly aligned film of semiconducting single-walled carbon nanotubes. The s-SWCNTs are applied in controlled ‘doses,’ which allows for the rapid sequential deposition of narrow films or ‘stripes’ with continuous control over width, density and periodicity. The film can be incorporated in high performance field effect transistors and other devices including displays, sensors, biosensors and heterojunction devices (e.g., solar cells).
