Nanocrystalline nickel-oxide-based thin films were prepared by advanced reactive gas deposition, and the response of these films to formaldehyde was studied by fluctuationenhanced sensing. Morphological and structural analyses showed porous deposits of nickel oxide particles with face-centered cubic structure. Resistance fluctuations were measured upon exposure to ethanol, formaldehyde and methane at 200 °C. Power density spectra were used to quantify the response. The response to formaldehyde was higher than to ethanol at 200 °C, and no significant response was observed for methane thus demonstrating some gas-species selectivity.
