Journal ArticleDOI
Sensors for sub-ppm NO2 gas detection based on carbon nanotube thin films
TL;DR: In this article, carbon nanotubes (CNTs) deposited by plasmaenhanced chemical vapor deposition on Si3N4/Si substrates have been investigated as resistive gas sensors for NO2.
Journal ArticleDOI
XPS studies on SiOx thin films
TL;DR: In this article, the surface stoichiometry of SiO x thin films (x = 1-2) has been studied by means of X-ray photoelectron spectroscopy, and the presence of three Si oxidation states (SiO 2, SiO, Si 2 O 3 ) has been observed through an analysis of the Si2p line shape and the intensity variation of these different silicon oxide signals, as a function of the oxygen content.
Journal ArticleDOI
NO2 and CO gas adsorption on carbon nanotubes: Experiment and theory
Sandro Santucci,Silvia Picozzi,F. Di Gregorio,Luca Lozzi,Carlo Cantalini,Luca Valentini,Jose Maria Kenny,Bernard Delley +7 more
TL;DR: In this paper, a combined experimental and theoretical study on carbon nanotube (CNT) based system for gas sensing applications is reported, in which the electrical resistivity of the CNT film shows a semiconducting-like temperature dependence and a p-type response with decreasing electrical resistance upon exposure to NO2 gas (100 ppb).
Journal ArticleDOI
NO2 sensitivity of WO3 thin film obtained by high vacuum thermal evaporation
Carlo Cantalini,Hong-Tao Sun,Marco Faccio,Mario Pelino,Sandro Santucci,Luca Lozzi,Maurizio Passacantando +6 more
TL;DR: In this paper, the gas sensitivity, selectivity and stability properties of WO 3 thin films for the detection of NO 2 gas in the concentration range 0.2 -5 ppm, have been evaluated and discussed in the light of the preparation conditions and working temperature.
Journal ArticleDOI
Highly sensitive and selective sensors based on carbon nanotubes thin films for molecular detection
TL;DR: In this paper, the electrical response of carbon nanotubes (CNTs) thin films to NO 2, CO, NH 3, H 2 O and C 2 H 5 OH for gas sensing applications is reported.
