Improvement of gas-sensing performance of TO8C monolayers as high-efficient room-temperature NO and NO2 gas sensors induced by electric field

Results in Physics, Journal Year: 2024, Volume and Issue: 61, P. 107770 - 107770

Published: May 17, 2024

The gas-sensing application potential of the TO8C monolayer for target gases (NO, NO2, CO, CO2, NH3, CH4, H2O, and H2) was systematically investigated via DFT calculations. Only NO NO2 adsorption can tune electronic properties monolayer. Since weak strength is unfavorable sensor device, E-field modulation applied. Except as enhancement into desired ranges −0.14 ∼ −0.21 V/Å (0.08 0.12 −0.26 −0.29 NO2) makes semiconducting transfer conducting properties, indicating sensitivity towards also effectively improved. However, adsorbed with other were hardly changed by above-mentioned E-fields. When applied E-fields in −0.12 −0.17 (or V/Å), maintained existence humidity, that determinate much favorable TO8C-based to detect without considering whether humidity exists. Our findings reveal monolayers are compelling feasible candidates resistance-type sensors at room temperature under modulation.
