Talk delivered at the 13th Spanish Conference on Electron Devices, CDE 2021, Sevilla (Spain) 9 June 2021 - 11 June 2021, 171142., This work reports on two-dimensional MoS 2 nanomaterial-based resistive gas sensors and their response to sub-ppm NO 2 concentrations. The sensitive material was prepared by drop-casting MoS 2 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 NO 2 concentrations as low as 20 ppb at room temperature. The n-type MoS 2 sensing mechanism is here discussed., 10.13039/501100004837-Spanish Ministry of Science and Innovation (Grant Number: PID2019-107697RB-C43)
