Abstract
This work reports on two-dimensional MoS2 nanomaterial-based resistive gas sensors and their response to sub-ppm NO2 concentrations. The sensitive material was prepared by drop-casting MoS2 nanosheet dispersions on silicon nitride suspended membranes. The sensor response was studied at operating temperatures up to 300 °C. The fabricated sensors provided good responses to NO2 concentrations as low as 20 ppb at room temperature. The n-type MoS2 sensing mechanism is here discussed.
