The Pickup Stick Transistor
Abstract
Precise control over the electronic properties of the carbon nanotubes is key to their practical application in plastic electronics. In the present work, we have extended carbon nanotube functionalization via a 2-2 cycloaddition to electron withdrawing non-fluorinated olefins as well. Our results show that this is a fairly general approach, independent of specifics of the adderid, to converting the grown mixture of metal and semiconductor tubes into high mobility semiconducting tubes without tedious of separation requirements. Thin film transistors fabricated with functionalized tubes exhibit mobilities of 10-30 sq cm/sec and on/off ratios in excess of 10(exp 6). This simple functionalization approach represents a low cost path to high performance semiconducting inks for printable electronics.
