Enhanced hydrogen gas sensitivity employing sputtered deposited NiO thin films
2019
Iraqi Journal of Physics
Key words In this work, nickel oxide thin films have been successfully deposited on glass substrates by sputtering technique at different temperatures, and explored as a fast response sensor to hydrogen reducing gas. The nickel oxide sensor exhibits an increase of the conductance upon exposure to hydrogen gas of various concentrations at different operating temperatures. Pure sputtered NiO sample showed excellent sensitivity S of 1488% to hydrogen gas at the optimum H 2 : air concentration of
