Abstract
The authors report about characterization of chalcogenide-based thin films, as a materials for gas-sensing applications. The sensing behavior of the As-S-Te films was tested with environmental pollutant gases such as NO2, CO, and SO2. A significant sensitivity has been observed for nitrogen dioxide. The detection range for NO2 was between 0.95-1.9 ppm in ambient air. The response and the recovery time is rapid, with good reproducibility and high sensibility. All the measurements were performed at room temperature. Gas-sensing applications are considered.
