Abstract: A process for making a stoichiometric and crystalline thin film CuO catalytic layer atop a gas sensing layer for the detection of dilute sulfur compound gases. The sensing layer is made using dual ion beam sputtering, where an argon ion beam sputters targets comprising Sn or its oxides, and a pure or highly concentrated oxygen ion beam is simultaneously deposited on a substrate. The catalytic layer is made using dual ion beam sputtering, where an argon ion beam sputters targets comprising CU or its oxides, and a pure or highly concentrated oxygen ion beam is simultaneously deposited on a substrate.
