ABSTRACT

The electronic and transport properties of armchair silicene nanoribbons (ASiNRs) were observed for sensing N2O gas molecules using density functional theory combined with non-equilibrium Green’s function. The main focus of this paper was on the detection of N2O gas molecule using ASiNRs. The plants along with the microbes in the soil are the sources of N2O, which contributes to the global warming 310 times that of carbon dioxide, so there is an utmost need of sensing this gas. The minimal band gap of pristine ASiNRs made it a semimetal, which was tuned on the adsorption of nitrous oxide, making it a semiconductor, thereby finding applications in electronics. The results showed that ASiNRs could be used as potential sensors for sensing N2O down to a single molecule level.
