This work presents new results on the gas sensing study of CNT-SnO2 nanocomposite thin film prepared by e-beam evaporation process. The SnO2 gas sensing layers have been achieved with varying CNT concentration. Structural and morphological characterization by means of SEM TEM and XRD indicate that CNTs is incorporated in form of small fragments uniformly dispersed within SnO2 crystal and CNT inclusion...
In this work, we investigate gas sensing characteristics of a new composite material, ZnO doped TiO2. TiO2/ZnO layers have been deposited by ion-assisted e-beam evaporation with different doping concentrations. Structural and morphological characterization has been carried out by means of SEM, XRD and EDX in order to correlate structural properties with gas sensing behavior. Gas-sensing characterizations...
This work presents new results on the gas sensing studies of WO 3 and MO3 doped TiO2 thin films prepared by ion-assisted e-beam evaporation process. N-type TiO2 gas-sensing layers have been deposited with different doping concentrations. Structural and morphological characterization has been carried out by means of SEM and XRI in order to correlate physical properties with gas sensing performance...
Thin films of cobalt oxide have been prepared by reactive sputtering and the spinel CoCo2O4 structure together with p-type sensing behavior has been achieved. Structural and morphological studies have been carried out by means of SEM, TEM and XRI in order to investigate the correlation between the deposition parameter and the sensing performance. The films proved to be sensitive to ethanol, carbon...
