Molecular Monolayers as Semiconducting Channels in Field Effect Transistors... 

As discussed above, the driver for many printed electronics applications is the printed transistor. The printed transistor is essentially a thin film transistor fabricated using printable materials. In other words, in its ultimate implementation, all three major material components of the printed transistor, i.e., the conductive electrodes, the insulating gate dielectric, and the semiconducting channel material, are printed. 

The uniquely high mobility displayed by SWNT (146, 147) makes them attractive for applications in nanodevices, such as thin-film transistors (TFT), which could be produced by solution-processed random networks of SWNT. An optimum TFT would be composed entirely of semiconducting nanotubes, since their performance is limited by the presence of metallic tubes. It has been proposed that even below the percolation threshold of metallic tubes, electron hopping or tunneling may occur between neighboring metallic tubes (148). This electron channeling reduces the on/off ratio and therefore, the overall performance of the transistor. Removal of metallic nanotubes from the network has been achieved by electron breakdown (149, 150).
