Abstract

The transport properties of a $$\hbox {Zn}_{2}\hbox {SnO}_{4}$$ Zn 2 SnO 4 device along with adsorption properties of $$\hbox {NO}_{2}$$ NO 2 gas molecules on $$\hbox {Zn}_{2}\hbox {SnO}_{4}$$ Zn 2 SnO 4 (ZTO) molecular devices are investigated with density functional theory using the non-equilibrium Green’s function technique. The transmission spectrum and device density of states spectrum confirm the changes in HOMO–LUMO energy level due to transfer of electrons between the ZTO-based material and the $$\hbox {NO}_{2}$$ NO 2 molecules. I–V characteristics demonstrate the variation in the current upon adsorption of $$\hbox {NO}_{2}$$ NO 2 gas molecules on the ZTO device. The findings of the present study clearly suggest that ZTO molecular devices can be used to detect $$\hbox {NO}_{2}$$ NO 2 gas molecules in the trace level.
