Abstract
A novel room-temperature (RT) resistive-type NO2 gas sensor was developed by utilizing ZnO nanowires as sensitive materials and metallic single-walled carbon nanotubes (m-SWCNT) as electrodes where both of them were fabricated by spray deposition process. The ZnO/m-SWCNT sensing devices showed better sensing response to NO2, as compared to traditional ZnO/Au sensing devices, which possess opposite sensing response. This can be attributed to different Schottky junction barrier characteristics at ZnO/m-SWCNT interface. This work paves the way to explore effective sensing and electrodes for future novel NO2 gas sensors in practical and rigid gas sensing system applications.
