Aligned single-walled carbon nanotube thin-film transistor arrays for transparent electronics

The implementation of mechanically flexible and optically transparent nanoscale transistors could enable high definition, large-area, low-cost, low-power and light-weight active matrix displays. Transparent thin film transistors (TFTs) fabricated with semiconductor nanowires and a randomly aligned networks of carbon nanotubes have been previously reported. In this paper, we report fully transparent TFTs based on well-aligned single-walled carbon nanotube transistor (SWCNT) arrays. These devices provides higher performance the prior nanowire/CNT network transparent devices, achieve -83% transparency on quartz substrate over the visible wave-length range and are suitable for integration with organic light emitting diodes.
