This contribution presents the main studies on the CNTFET based gas sensors obtained using Single-Walled Carbon Nanotubes mats (SWCNTs) as channel. Although these devices have allowed one to achieve sensors with an impressive sensitivity compared to existing technologies, the physical interpretation of the effect of interaction between the gas molecules and the CNTFETs has not yet been clarified. Concerning selectivity, we will deal with the main routes that have been proposed to overcome this problem: functionalization using polymers, electrodes metal diversification, metal decoration of SWCNT mats.
Parmi les détecteurs de gaz basés sur des transistors à effet de champ à nanotubes de carbone (CNTFET) ceux qui utilisent comme canal des nattes de nanotubes de carbone à paroi simple (SWCNT) sont passés en revue dans la présente étude. Bien que ces dispositifs aient permis de réaliser des détecteurs dont la sensibilité est impressionnante en comparaison avec les technologies existantes, l'interprétation physique de l'effet de l'interaction entre les molécules de gaz et les CNTFET n'a pas encore été clarifiée. En ce qui concerne la sélectivité, nous nous intéresserons aux diverses voies proposées pour surmonter ce problème : fonctionnalisation par des polymères, diversification des électrodes métalliques, décoration métallique des nattes de SWCNT.
