A series of gas sensing layers based on indium oxide doped with gold were prepared by using the aerosol technology fordeposition as the active contact layer in a metal oxide semiconductor capacitive device. The interaction between the measuredspecies and the insulator surface was quantified as the voltage changes at a constant capacitance of the device. The sensor propertieswere investigated in the presence of H2, CO, NH3, NO, NO2 and C3H6 at temperatures between 100–400 oC. Significant differencesin the morphology of the layer and its sensitivity were noted for different preparation methods and different gas environments.
