Discovery Project: Suspended Single-Walled Carbon Nanotube-Based Gas Sensors

Résumé des résultats (Abstract) (Anglais)

The focus of this discovery project is the design, fabrication, modeling and systematic evaluation of carbon nanotube-based (CNT) gas sensor demonstrators for industrial and household applications. The proposed solution consists in a suspended single-walled carbon nanotube (SWNT) field effect transistor device (FET) that exploits substantial changes in the electronic transport properties of carbon nanotubes manifested upon exposure to given chemical analytes (chemFET principle). Nitrogen dioxide (NO2) has been selected as the gas of interest for fire detection and exhaust-gas monitoring applications.
