Adsorption of habitat and industry-relevant molecules on the MoSi2N4 monolayer

A. Bafekry et al.

Summary: Theoretical calculations reveal that the adsorption of certain gas molecules on the MSN monolayer surface can preserve its semiconductor character while altering its electronic properties. Spin polarization with magnetic moments can be introduced by the adsorption of certain molecules. The band gap and magnetic moment of the adsorbed MSN monolayer can also be modulated by the concentration of specific molecules, suggesting high application potential for gas detection.
