Subject area: Science,Engineering and Technology  ·  Area of research: 2-D materials

Abstract

In this work, we use first-principles calculations to examine the potential of copper (Cu)-doped two-dimensional (2D) MoSe₂ monolayer for NH3 capture. Cu-doped MoSe₂ electronic properties in the context of NH3 sensing have been comprehensively investigated using Density Functional Theory (DFT). The negative formation and binding energy of -6.62 and -4.78 eV show the electronic stability of undoped Cu-doped MoSe2 ML. Band structure, sensitivity, recovery time, charge transfer, and adsorption energy of SO₂ molecules on the doped monolayer are all examined. Following NH3 adsorption, the results show significant alterations in the electromic and sensing properties of Cu-doped MoSe₂, highlighting its potential as a reliable and effective material for gas sensing applications.
