Hu, Fa-Fei (author), Tang, H. (author), Ye, H. (author), Chen, X. (author), Zhang, Kouchi (author)The sensing behavior of monolayer tin sulfide (SnS) for four gas molecules (NH<sub>3</sub>, NO<sub>2</sub>, CO, and H<sub>2</sub>O) are studied by the first-principle calculation based on density-functional theory. We calculate adsorption energy, adsorption distance, and Hirshfeld charge to estimate the adsorption ability of monolayer SnS for...journal article 2017
