(398e) Carbon Nanotube Networks

Single-walled carbon nanotubes (SWNTs) exhibit superior electronic and mechanical properties, in addition to environmental stability, yielding ideal components for flexible electronic devices. While devices based on a single SWNT have yielded interesting findings on their fundamental charge transport, obstacles their device fabrication still inhibit practical implementation. Individual SWNT-based devices are not feasible for large scale integration at this time, however, recently developed random nanotube networks offer an excellent compromise with on/off ratios up to 105 upon optimization of tube chirality ratio and/or device geometry. Still, the nature of SWNTnt randomness in terms of chirality, tube density, and bundling makes device reproducibility poor, greatly inhibiting high performance.

In this talk, I will present our recent work in sorting SWNTs using functionalized surfaces and applications of sorted and aligned SWNTs for sensor applications
