摘要
In this paper, we describe the optical and electrical gas-sensing properties of InxOyNz films with an ultrathin gold promoter overlayer. We have fabricated InxOyNz films with a nanocrystalline porous structure by RF-sputtering in Ar/N-2 followed by an annealing process. Gold particles with 20-30-nm diameter have been formed on top of the InxOyNz films by dc sputtering and an annealing process. We have investigated the optical H-2- and NO2-sensing properties (change of absorbance) and also the electrical sensing effect (change of electrical resistance) for these two gases. A combined optical/electrical sensor for H-2/NO2 is proposed.
