Here we report a simple and valid method to fabricate printed top-gate thin-film transistors (TFTs) with based on poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(1,4-benzo-2,1-3-thiadiazole)] (PFO-BT) sorted semiconducting carbon nanotubes (SWNTs) from arc discharge carbon nanotubes. Sorted sc-SWCNT inks were directly [...]

Wafer-scale integration of in-situ grown carbon nanotube membranes: a platform to study electrical properties

Le Poche H., Guerin H., Fournier A., Ramos R., Fayolle M., Delaunay M., Dijon J., Ionescu A.M., CEA-Liten, FR

Dense arrays of horizontal carbon nanotubes (CNTs) connected between two metallic electrodes and either supported on a silicon dioxide layer or suspended above a third gate electrode constitute a basic building block to achieve CNT-based [...]

Harnessing the resistive-elastic behavior of novel CNT-graphene hybrid foams for practical sensing applications

Wolmarans F., Van H.H., Li S.J., Liu T., Liu T., Zhang M., Florida State University, US

Carbon nanotube (CNT) foam and aerogels hold promise in the area of strain sensors because of their resistive-elastic behavior under compressive strain. To date one of the largest obstacles in the area of CNT foam [...]
