CNTFETs fabricated using an Original Dynamic Air-Brush technique for SWCNTs deposition : application to gas sensing

Bondavalli P., Gorintin L., Feugnet G., Thales Research and Technology, FR

This contribution deals with Carbon Nanotubes Field Effect transistors (CNTFETs) based gas sensors fabricated using a completely new dynamic air-brush technique for SWCNTs deposition. More precisely, we have developed a machine which allows us the [...]

Carbon nanotubes transistors based Selective Gas sensors : from laboratory to mass production

Gorintin L., Thales Research and Technology, FR

Gas sensing Property of Carbon NanoTube (CNT) transistors are known for several years to be extremely sensitive to gases and thus have been proposed as gas sensors for several applications. But their versatility and their [...]

Highly selective sensing of DMMP and NH3 using CNTFET array based gas sensors obtained using Spray-gun technique and fabricated with different metal electrodes to achieve gas electronic fingerprinting

Bondavalli P., Legagneux P., Pribat D., Gorintin L., Thales Research and Technology, FR

This paper deals with the prove of concept of an highly selective gas sensor based on CNTFETs which exploits the extremely sensitive change of the Schottky barrier heights between SWCNTs and metal electrodes. Specifically, the [...]
