The physical properties and the effect of effective surface area (ESA) on the sensing properties of tin dioxide [SnO2] thin films in air and propane [C3H8] atmosphere as a function of operating temperature and gas concentration have been studied in this paper. SnO2 thin films with different estimated thicknesses (50, 100 and 200 nm) were deposited on glass(More)
Chromium and ruthenium-doped zinc oxide (ZnO:Cr) and (ZnO:Ru) thin solid films were deposited on soda-lime glass substrates by the sol-gel dip-coating method. A 0.6 M solution of zinc acetate dihydrate dissolved in 2-methoxyethanol and monoethanolamine was used as basic solution. Chromium (III) acetylacetonate and Ruthenium (III) trichloride were used as(More)
Simulation software is a fundamental tool that should be used when designing systems dealing with circuit interaction, for instance. Nevertheless, there exist some inconveniences that limit and make specific software hard to use in this task. On one side, it may require a large processing hardware capacity, and on the other, simulation time increases(More)
Gallium, aluminum, fluorine, and indium doped ZnO (ZnO:Ga, ZnO:Al, ZnO:F, and ZnO:In) thin films have been deposited by the chemical spray technique on soda lime glass substrates. The effect of different dopant elements on the electrical, optical, structural, and morphological properties has been investigated. The X-ray diffraction (XRD) patterns reveal(More)
Simulation software is a fundamental tool that should be used when designing systems dealing with electro-thermal interaction, for instance. Nevertheless, there exist some inconveniences that limit and make specific software hard to use in this task. On one side, it may require a large processing hardware capacity, and on the other, simulation time(More)
Gas sensors based on various principles and configurations have been studied for several years. Some of them are based on resistance variation of sensing layers. On the other hand, floating-gate MOSFETs can modify its threshold voltage by means of a chemical reaction. Here a study is made to prove that the charge produced by such chemical reaction can(More)
