This Nano Forum covers recent emerging area of singlewalled carbon nanotubes for the applications to flexible transparent conducting films and thin film transistors that have emerged as low cost, large area alternatives to individual SWCNT devices and have been the subject of numerous fundamental studies. Specifically, SWCNT thin films can achieve transparency of >80% with sheet resistance values approaching that of indium tin oxide (ITO). In addition, thin films transistors from SWCNTs can achieve mobilities of up to 1000 cm2/V-s with on/off ratios of >105 The breakthroughs, issues, and the remaining problems related to the fabrication of random networks and device performances will be addressed from the world-leading scientists in this Forum.
