| Abstract Scope |
Currently there are limited reports on the use of two-dimensional WSe2 towards gas sensors. Due to the intrigue in exploring this area further, the large surface-area to volume ratio of WSe2 due to its van der Waals characteristic provides potential for enhanced interactions with target analytes. In this work, we fabricated a chemically exfoliated WSe2 device, contacted with metal electrodes where its response to incoming gasses was examined. The films were formed using spin coating and inkjet printing and electrically contacted in a two-terminal configuration. The structural properties of the films were examined using various microscopy and spectroscopy tools such as scanning electron microscopy, Raman and photoluminescence spectroscopy. This allowed us to validate morphology and chemical fingerprints of the films, and correlate this to our electronic transport data with various incoming gasses. From our work, the WSe2 gas sensors show a promising platform for gas-sensing applications using novel materials.
