Abstract
In this study, self-bridged ZnO nanowires were grown by a simple annealing process and their humidity sensing properties were investigated. The wurzite structure and high crystallinity of the ZnO nanowires were confirmed by XRD and PL analyses. The humidity sensing characteristics varied exponentially with increasing humidity. A conventional sensor device should have good repeatability and superior humidity sensing response. The experimentally obtained response and recovery times of the ZnO nanowires were 35.3 and 32.6s, respectively. A possible humidity sensing mechanism is also proposed. (c) 2018 Elsevier B.V.
