چکیده

We introduce a simple solution-based method for the fabrication of highly oriented carbon nanotube (CNT) arrays to be used for thin-film transistors. We exploit the liquid-crystalline behavior of a CNT solution near the receding contact line during tilted-drop casting and produced long-range nematic-like ordering of carbon nanotube stripes caused by confined micropatterned geometry. We further demonstrate that the performance of thin-film transistors based on these densely packed and uniformly oriented CNT arrays is largely improved compared to random CNTs. This approach has great potential in low-cost, large-scale processing of high-performance electronic devices based on high-density oriented CNT films with record electrical characteristics such as high conductance, low resistivity, and high career mobility.

Pentacene-carbon nanotubes: Semiconducting assemblies for thin-film transistor applications

We demonstrate an alternative path for achieving high-transconductance organic transistors by assembling bilayers of pentacene onto random arrays of single-walled carbon nanotubes. We show here that, by varying the connectivity of the underlying nanotube network, the channel length of a thin-film transistor can be reduced by nearly two orders of magnitude—thus, enabling the increase of the devi...
